However, recent scholarship increasingly emphasizes the role of off-balance-sheet fiscal agencies (OBFAs)—entities distinct from the treasury but tasked with similar fiscal activities, often backed by implicit or explicit state guarantees. This creates a complex and historically contingent “fiscal ecosystem,” shaped by political, economic, and legal dynamics. Using Germany as a case study, this article develops a methodology to categorize and map its extensive ecosystem of OBFAs, which number in the tens of thousands. These entities are analyzed in relation to their legal status, revenue models, and debt-issuance practices, with particular attention to their alignment with Germany’s constitutional debt brake and EU fiscal rules. The German case illustrates how states extend their fiscal reach by operating a more complex web of balance sheets than is often thought.</p> https://escholarship.org/uc/item/8g1346kh Thu, 18 Jun 2026 00:00:00 +0000 Laudage, Gregor Haas, Armin Guter-Sandu, Andrei Murau, Steffen https://escholarship.org/uc/item/9rh734gg Front Matter v6 iss1 https://escholarship.org/uc/item/9rh734gg Tue, 16 Jun 2026 00:00:00 +0000 Editors, JLPE https://escholarship.org/uc/item/8bn3h2cx <p>This review essay engages with various conceptualizations of the “capitalist state” and “state capitalism” within four newly published books. It posits that the capitalist state is not a homogeneous category—that the “mature independence of the economic sphere from the political sphere” in liberal capitalism and their “immature independence” in state capitalism render the role of the state in each geography different while producing distinct geopolitical structures within the global economic order. The essay argues that the extraterritorial liberal capitalism of the Anglo-Saxon sphere has historically produced and simultaneously peripheralized state capitalism outside this sphere. State capitalism has, in turn, posed threats to free competition and profitability rates of liberal capitalism, requiring intervention by the hegemonic power arising from liberal capitalism to tackle market distortion. As such, debates around the “return of geopolitics” to international law should... https://escholarship.org/uc/item/8bn3h2cx Tue, 16 Jun 2026 00:00:00 +0000 Mansouri, Negar https://escholarship.org/uc/item/8864g4d3 <p>High-profile pronatalist supporters of reproductive genetic technologies have thrust these technologies into the national spotlight in the US, reprising questions about the relation between reproductive biotechnologies and eugenics. This article develops the concept of neoliberal eugenics to reframe common understandings of this issue. Neoliberal eugenics refers to the way that neoliberalism facilitates eugenic logic and outcomes through a framework of “choice.” The article draws on scholarship in disability justice and reproductive justice to articulate the limitations of choice before analyzing specific new reproductive genetic technologies and their political economy. The concept of neoliberal eugenics also reveals the flaws in judges’ reasoning in decisions about reproductive technology and eugenics. In short, the article argues that we need a new theory of neoliberal eugenics to understand the burgeoning reproductive biotechnology industry. That theory must consider political... https://escholarship.org/uc/item/8864g4d3 Tue, 16 Jun 2026 00:00:00 +0000 Denbow, Jennifer https://escholarship.org/uc/item/38x1579p Review of Trevor Jackson, Impunity and Capitalism: The Afterlives of European&nbsp;Financial Crises, 1690–1830 (Cambridge University Press, 2022) https://escholarship.org/uc/item/38x1579p Tue, 16 Jun 2026 00:00:00 +0000 Hamilton, Matthew https://escholarship.org/uc/item/2p18f04h Review of Edward Jones Corredera, Odious Debt: Bankruptcy, International Law, and the Making of Latin America (Oxford University Press, 2024) https://escholarship.org/uc/item/2p18f04h Tue, 16 Jun 2026 00:00:00 +0000 Carvalho, Fabia Fernandes https://escholarship.org/uc/item/1jn03134 <p>Human activity is dramatically reducing global biodiversity. In response, legal decision-makers have deployed regulations aimed at minimizing the impact of the sixth mass extinction event in Earth’s history. However, environmental law has recurrently failed to arrest rates of biodiversity loss. As such, legal scholars have proposed myriad reforms to overhaul the legal protection of biodiversity, ranging from introducing a crime of “ecocide” to granting legal personality to nonhumans. Yet there is a gap in the literature concerning the tendency of these novel proposals to reproduce the limitations of traditional methods. This article addresses that gap by critically reviewing the literature on the ontological tensions between Western-descended legal systems and the science of ecology. It argues that these tensions produce ecological “translation errors” within law that run deeper than is often acknowledged. The article concludes that increased skepticism—but not apathy—toward... https://escholarship.org/uc/item/1jn03134 Tue, 16 Jun 2026 00:00:00 +0000 Sagar, Andrew https://escholarship.org/uc/item/16n867tz <p>This research examines the international climate change regime, critically assessing the extent to which it is underpinned by the growth-oriented, mainstream conceptualization of sustainable development. The study first outlines the shortcomings characterizing the concept of sustainable development, as well as differences which exist between its mainstream and more progressive conceptualizations. Subsequently, it adopts a post-sustainable-development perspective to identify elements within the international climate change regime that reflect and normalize the mainstream conceptualization of sustainable development. Although climate change treaties “shall be based on best available scientific knowledge,” the literature reveals that mainstream sustainable development ontology is built upon shaky assumptions, including the feasibility of decoupling global economic growth from ecological pressures. Nonetheless, the three climate change treaties have increasingly been influenced... https://escholarship.org/uc/item/16n867tz Tue, 16 Jun 2026 00:00:00 +0000 Talenti, Roberto https://escholarship.org/uc/item/0bs1258k <p>The article argues that labor litigation helps to sustain, rather than interrupt, the process of worker exploitation. Using legal claims raised by Uber drivers and Deliveroo riders in the UK as a backdrop, it focuses on undue exploitation—exploitation beyond the limits set by law—as a mechanism that facilitates capital accumulation while hedging against the liability this mode of exploitation imposes. While assuming this outcome is socially undesirable and ideally curtailed by law, the article shows that the legal framework of labor litigation produces two complementary effects that reinforce exploitation through the embeddedness of irresponsibility. First, it disassembles the reciprocity between exploitation and liability, enabling extraordinary profit flows for exploiters. Second, it normalizes residual profits that persist beyond court awards. These effects frame exploitation as a gamble that will generally pay off, all the while embedding its social effects at a level no... https://escholarship.org/uc/item/0bs1258k Tue, 16 Jun 2026 00:00:00 +0000 Astone, Daniel P. https://escholarship.org/uc/item/0sf8h00t Since enactment of the major federal environmental statutes of the 1970s, U.S. toxics policy has departed from a primary goal of controlling pollution to increasingly focus on information transparency. One of the most prominent right-to-know laws, California's Proposition 65, has been in force since 1986, yet there is scant literature on its systemic impacts. We conducted 32 semi-structured interviews with business leaders representing some of the largest actors in their sectors to investigate Proposition 65's impacts. We found that Proposition 65 prompts changes to consumer product ingredients and improves supply chain transparency. Businesses (re)formulated products for national and even international markets based on this state law, highlighting the leverage of environmental regulations in a large state like California. Information-forcing laws can thus protect public health in ways that transcend the immediate impacts of transparency with the public about product ingredients.... https://escholarship.org/uc/item/0sf8h00t Thu, 7 May 2026 00:00:00 +0000 Ohayon, Jennifer L Polsky, Claudia https://orcid.org/0009-0002-4110-3164 Schwarzman, Megan R https://escholarship.org/uc/item/7bq9h0sf Two meta-theoretical traditions mark research on conflict resolution in organizations: the rationalist tradition, which portrays organizations as goal-directed collectivities and conflict resolution as a threat to efficiency and performance; and the cultural tradition, which portrays organizations as normative collectivities constituted by ongoing social interaction, interpretive dynamics, and institutional environments, and emphasizes the interplay of law and social inequalities in interpersonal and collective organizational conflict resolution. Within these traditions, we distinguish between structural and processual styles of research, noting the empirical methods favored in each tradition, research that blurs the boundaries between the traditions, and vanguard scholarship. Finally, we discuss several potential areas of research that could enhance meaningful intellectual exchange between the traditions. https://escholarship.org/uc/item/7bq9h0sf Mon, 13 Apr 2026 00:00:00 +0000 Morrill, Calvin Rudes, Danielle S https://escholarship.org/uc/item/5xt3k3hs Culture has become a legitimate concern and part of the basic conceptual toolkit in much of contemporary organization theory. This article historically traces the contested place of culture in organization theory—from acultural rationalist theorizing at the turn of the twentieth century; to the accidental “discovery” of shop floor culture by human relations scholars in the 1920s; to mid-twentieth-century explorations of informal and institutionalized relations in organizations; to present-day approaches that blend concepts from organizational culture frameworks, neoinstitutional analysis, sociology of culture, and social movement theory. This historical backdrop provides a context for raising several research questions relevant to organizational change, boundaries, and deviance. In closing, the author suggests that an analytic nexus between culture, power, and agency is emerging in contemporary organization theory that ultimately may yield a theory of society. https://escholarship.org/uc/item/5xt3k3hs Mon, 13 Apr 2026 00:00:00 +0000 Morrill, Calvin https://escholarship.org/uc/item/5cg9v9hm In this article, we analyze ethnoracial patterns in youth perceptions and responses to rights violations and advance a new model of legal mobilization that includes formal, quasi-, and extralegal action. Slightly more than half of the 5,461 students in our sample reported past rights violations involving discrimination, harassment, freedom of expression/assembly, and due process violations in disciplinary procedures. Students, regardless of race, are more likely to take extralegal than formal legal actions in response to perceived rights violations. Self-identified African American and Latino/a students are significantly more likely than white and Asian American students to perceive rights violations and are more likely to claim they would take formal legal action in response to hypothetical rights violations. However, when they perceive rights violations, African American and Asian American students are no more likely than whites to take formal legal action and Latino/a students... https://escholarship.org/uc/item/5cg9v9hm Mon, 13 Apr 2026 00:00:00 +0000 Morrill, Calvin Tyson, Karolyn Edelman, Lauren B Arum, Richard https://escholarship.org/uc/item/11w431kw ▪ Abstract This review considers a class of political activity that has largely been ignored by researchers extending social movement theory into organizations: covert political conflict. Although much of the literature we discuss focuses on contemporary corporations where the bulk of research on covert conflict has occurred, we also explore studies of covert conflict in a range of historical and organizational contexts that fall outside the contemporary work world. As we define it, covert political conflict encompasses four interrelated elements: contestation of institutionalized power and authority, perceptions of collective injury, social occlusion, and officially forbidden forms of dissent. Beyond these elements, covert conflict varies in its material and symbolic forms, collective dimensions, social visibility, and outcomes. We also examine explanatory approaches for covert conflict at the micro, organizational, field, and macro levels of analysis. Finally, we suggest a number... https://escholarship.org/uc/item/11w431kw Mon, 13 Apr 2026 00:00:00 +0000 Morrill, Calvin Zald, Mayer N Rao, Hayagreeva https://escholarship.org/uc/item/42v6t2qv ‘Blawius paratissimus est excudere Niciana omnia’ https://escholarship.org/uc/item/42v6t2qv Wed, 25 Feb 2026 00:00:00 +0000 Nelson, Jennifer K https://escholarship.org/uc/item/5k13v3xm Pax Economica and Its Discontents https://escholarship.org/uc/item/5k13v3xm Wed, 11 Feb 2026 00:00:00 +0000 Grewal, David Singh https://escholarship.org/uc/item/9fb2q020 With the rapid expansion of digital technologies in recent years, the “attention economy” has attracted the interest of academics and policymakers. At the same time, the rise of the neo-Brandeisian approach to antitrust has caused regulatory bodies to investigate the market power of technology companies. This article analyzes the role of antitrust in the attention economy. First, it defends user autonomy as the standard for antitrust regulation, and second, it argues that facilitating competition must not be the orienting goal for regulating markets of attention that threaten user autonomy. Enhancing competition without restraints on the practices of technology companies within those markets is not only insufficient to address the fundamental harms to user autonomy that results from the attention economy, but may, in practice, exacerbate these harms. To address the problems of the attention economy, regulators must establish meaningful ex ante restrictions on the practices of... https://escholarship.org/uc/item/9fb2q020 Wed, 14 Jan 2026 00:00:00 +0000 Mariani, Isabella Luisa https://escholarship.org/uc/item/9z76x7jx Review of Gerald Epstein, Busting the Bankers’ Club: Finance for the Rest of Us (University of California Press, 2024) https://escholarship.org/uc/item/9z76x7jx Tue, 30 Dec 2025 00:00:00 +0000 Sengupta, Shohini https://escholarship.org/uc/item/8555p25c <p>This paper argues that decarbonization will fail to deliver climate justice unless the transition to clean energy confronts the racialized political economy that has historically structured extractive activity and shaped international economic law. Grounding its analysis in racial capitalism, the paper contends that the growing demand for critical minerals risks reproducing patterns of exploitation, expropriation, and expulsion. Using lithium extraction in Chile as a case study, it shows how colonial legacies, dictator-era neoliberal reforms, and present-day regulatory architectures governing foreign investment and natural resource extraction have prioritized investors over human rights and the environment. Recent decisions of the International Court of Justice and the Inter-American Court of Human Rights on climate change provide a normative counterweight to international investment law and potentially a pathway for inclusive and transformative reforms. By foregrounding racial... https://escholarship.org/uc/item/8555p25c Tue, 30 Dec 2025 00:00:00 +0000 George, Erika https://escholarship.org/uc/item/52h256gp <p>The way people treat each other and the way they treat their environment are inextricably intertwined. Thus, it is unsurprising that five centuries of colonialism, genocide, slavery, apartheid, and racial discrimination have produced climate change, mass extinction, desertification, deforestation, and polluted air, water, and lands. The West has used international law to institutionalize unaccountability for its racism and environmental harms. This article argues that international law’s inability to stem accelerating ecological decline is attributable to and inseparable from the discipline’s racism, and vice versa. This article explores five legal techniques—comparison, objectification, exploitation, taming, and extermination—that produce racist and environmentally harmful outcomes while cloaked in the legitimacy of the law. The racializing of nature and the naturalizing of race through international law depend on the erasure of subaltern worldviews. But another international... https://escholarship.org/uc/item/52h256gp Tue, 30 Dec 2025 00:00:00 +0000 Natarajan, Usha https://escholarship.org/uc/item/4r21v31z Review of Austin Frerick, Barons: Money, Power, and the Corruption of America’s Food Industry (Island Press, 2024) https://escholarship.org/uc/item/4r21v31z Tue, 30 Dec 2025 00:00:00 +0000 Saito, Carolina https://escholarship.org/uc/item/4rn2m88w Front Matter v5 iss4 https://escholarship.org/uc/item/4rn2m88w Mon, 29 Dec 2025 00:00:00 +0000 https://escholarship.org/uc/item/2qg8s9zw <p>This article examines the legal constitution of racialized climate injustice, assessing the racialized dynamics of property in the context of climate change. It explores these examples: first, the failure of the international climate regime to contest unjust appropriation of the atmosphere by industrialized countries regarding historical emissions; second, the limitations of the “no-harm” rule, which is effectively the internationalization of the domestic principles of the tort of nuisance, in providing compensation for the racialized harm caused by climate change; and third, how international investment law is allowing fossil fuel companies to seek compensation if governmental actions in response to climate concern impact their investment or hoped-for returns.</p> https://escholarship.org/uc/item/2qg8s9zw Mon, 29 Dec 2025 00:00:00 +0000 Dehm, Julia https://escholarship.org/uc/item/1f56v96k <p>This article examines how the enduring legacies of racial capitalism and discriminatory land&nbsp;policies shape climate vulnerability and adaptation in US cities, using Miami as a primary example. It&nbsp;highlights how flooding and heat waves disproportionately impact marginalized, historically&nbsp;disinvested neighborhoods, which are further threatened by displacement resulting from “climate&nbsp;gentrification.” Miami illustrates these dynamics, as affluent residents relocate from vulnerable coastal&nbsp;zones to higher-elevation, previously segregated neighborhoods, driving investment and property&nbsp;value increases that endanger longtime residents with displacement. The article explores how factors&nbsp;such as land use policy, zoning, and public investments embed racialized landscapes and drive&nbsp;displacement risk in these communities. The article calls for “just adaptation economies” that embed&nbsp;antidisplacement measures in resilience investments, support... https://escholarship.org/uc/item/1f56v96k Mon, 29 Dec 2025 00:00:00 +0000 Foster, Sheila R. https://escholarship.org/uc/item/02z8w43b <p>Climate change is a direct consequence of capitalism’s drive to maximize profits through the unbridled extraction of wealth from humans and nature, aided and abetted at every turn by law. In its voracious demand for cheap labor, cheap raw materials, and cheap waste disposal, capitalism has created a treadmill of fossil fuel–dependent production and consumption that has triggered a planetary emergency. It has also produced extreme economic inequality—a racialized division of wealth grounded in colonialism that enables the ultrarich to capture the spoils of the capitalist global economy while billions of people continue to live in extreme poverty. The articles published in this special issue examine the climate emergency and other ecological crises through the framework of racial capitalism. The theory of racial capitalism offers valuable insights into capitalism’s inherently eco-destructive logic and its reliance on racial stratification for the extraction of profit.</p> https://escholarship.org/uc/item/02z8w43b Mon, 29 Dec 2025 00:00:00 +0000 Atapattu, Sumudu Gonzalez, Carmen G. https://escholarship.org/uc/item/9fr9805d Rational Judicial Review: Constitutions as Power-sharing Agreements, Secession, and the Problem of Dred Scott https://escholarship.org/uc/item/9fr9805d Wed, 22 Oct 2025 00:00:00 +0000 Yoo, John https://escholarship.org/uc/item/41x196hd Advanced Introduction to Corporate Compliance by David Hess (Elgar 2024) https://escholarship.org/uc/item/41x196hd Wed, 8 Oct 2025 00:00:00 +0000 Bose, Debadatta https://escholarship.org/uc/item/5ds1c582 Front Matter v5 iss3 https://escholarship.org/uc/item/5ds1c582 Thu, 21 Aug 2025 00:00:00 +0000 Editors, JLPE https://escholarship.org/uc/item/4jz9b8b4 Review of Ignacio Cofone, The Privacy Fallacy: Harm and Power in the Information Economy (Cambridge University Press, 2023) https://escholarship.org/uc/item/4jz9b8b4 Sat, 16 Aug 2025 00:00:00 +0000 Pasquale, Frank https://escholarship.org/uc/item/6w0358qb Whether in the form of conceptual analysis or as grounding reduction, armchair theorising has been the main method of theory construction in general jurisprudence in the English-speaking world. Given important deficiencies in this way of proceeding, empiricist jurisprudence, particularly in the form of reductive naturalism, has emerged as an alternative to armchair theorising and has gained some support within the discipline. In this article, I argue that both of these methodological positions ultimately provide us with partial and thus inadequate explanations of the <i>complex</i> social phenomenon of law. In their failure, however, each position does get something right. I then further argue that to make good of these positions' strengths and simultaneously correct their shortcomings, we need to be able to navigate between the self-understanding of participants of the social practice of law and the viewpoints of social scientists and critical observers. https://escholarship.org/uc/item/6w0358qb Wed, 13 Aug 2025 00:00:00 +0000 Cortés-Monroy, Jorge https://escholarship.org/uc/item/1jb6b2hc As accelerating inequality careens into plutocracy, and America tilts toward autocracy, Karl Polanyi and Thomas Piketty have become key resources for understanding the link between the social exclusions of capitalism and democracy in crisis. This and its companion article (Somers 2022a) explore each of these thinkers and put them into dialogue to generate the outlines of a democratic political economy that I dub a predistributive democracy . Deconstructing capitalism’s moral economy of market justice , building on legal and economic institutionalism , and advocating a movement of countervailing power against escalating commodification and dedemocratization are central components of the project. The first article focused on Polanyi’s contribution to a predistributive democracy. This one engages Piketty’s work as it evolves from a bent toward economic naturalism to a robust institutionalism and an agenda for a participatory democratic socialism. Neither Polanyi nor Piketty... https://escholarship.org/uc/item/1jb6b2hc Mon, 11 Aug 2025 00:00:00 +0000 Somers, Margaret https://escholarship.org/uc/item/5s25j2t8 This article clarifies standards for evaluating whether a firm’s unilateral labor market conduct (wage suppression) violates antitrust law. It begins by analyzing suppression of collective bargaining (union busting) as conduct that can violate Section 2 of the Sherman Act. This article is the first to argue that wage suppression can violate Section 2 if the conduct (1) harms the competitive process within a labor market and increases monopsony, (2) tends to exclude law-abiding rivals from product or service markets, or (3) forecloses any adjacent market. Conduct that satisfies any of these three standards can be restrained with antitrust law. The antitrust standards presented are applicable to any kind of unilateral labor market conduct, including worker misclassification, wage theft, vertical restraints, restrictive covenants, employer-driven debt, or child labor. https://escholarship.org/uc/item/5s25j2t8 Sun, 10 Aug 2025 00:00:00 +0000 Swerdlow, Michael https://escholarship.org/uc/item/8qd4x8ss Prompted by the failed attempt to increase Australia’s central bank independence through removal of the government’s override, this article examines the central bank’s unelected authority to determine monetary policy and assesses whether this is justifiable in a democracy. It shows how political—and thus the people’s—power over economic management has diminished, positioning central bank independence within an antipopulist and antidemocratic movement in constitutionalism that has quasi-constitutionalized neoliberal approaches. In setting interest rates, central banks make decisions that involve big distributional trade-offs: sacrificing employment to achieve price stability; redistributing wealth from labor to capital. This article argues that such trade-offs necessitate retention of ultimate democratic control. The article thus supports retaining and refining Australia’s qualified central bank independence, and suggests novel policy options—compulsory savings and a job guarantee—to... https://escholarship.org/uc/item/8qd4x8ss Thu, 7 Aug 2025 00:00:00 +0000 Morris, Shireen https://escholarship.org/uc/item/8wm8z6hm Conservatives have long argued that progressive government policies tend to backfire (the “perversity thesis”). However, in American political discourse since the 1990s, this argument has been reframed in terms of “ unintended consequences.” The article explores this rhetorical shift by tracing the concept of “unintended consequences” from classical social theory to contemporary public policy debates. It finds that the term was originally associated with the notion of the “invisible hand” of the market, and gradually became aligned with the perversity thesis under the influence of neoconservatism, collective action theories, and Chicago School economics. The article argues that, due to this transformation, the “unintended consequences” rhetoric became especially valuable for neoliberalism, expressing both the efficacy of markets and the perceived failure of the democratic regulatory state. As such, the appeal to “unintended consequences” is revealed as an ideological stance rather... https://escholarship.org/uc/item/8wm8z6hm Wed, 6 Aug 2025 00:00:00 +0000 Faust, Abigail https://escholarship.org/uc/item/09c5q3dm Review of Jamee K.

I consider whether the concept of solidarity, especially solidarity in the face of legal repression, justifies a movement lawyer in using tactics that would otherwise be grounds for legal prosecution, professional discipline, or moral condemnation. Drawing on the long history of legal repression of progressive activism, including repression of progressive lawyers, this Essay proposes a way to think about lawyers aligning themselves with client activism while acknowledging the attraction to the notion that the lawyer's role as counselor or adviser does not permit lawyer involvement in conduct that is immoral, unfair, or of doubtful legality.

When two τ$$\tau $$-leptons are highly collimated, their visible decay products might overlap, degrading the reconstruction performance for each of the τ$$\tau $$-leptons. A dedicated treatment attempting to tag the τ$$\tau $$-lepton pair as a single object is required. The reconstruction algorithm is based on a large radius jet and its associated two leading subjets, and the identification uses a boosted decision tree to discriminate between signatures from τ+τ-$$\tau ^+\tau ^-$$ systems and those arising from QCD jets. The efficiency of the identification algorithm is measured in Zγ$$Z\gamma $$ events using proton–proton collision data at s=13$$\sqrt{s}=13$$ TeV collected by the ATLAS experiment at the Large Hadron Collider between 2015 and 2018, corresponding to an integrated luminosity of 139fb-1$$139\,\text{ fb}^{-1}$$.... https://escholarship.org/uc/item/42n9b8rk Tue, 3 Jun 2025 00:00:00 +0000 Aad, G Aakvaag, E Abbott, B Abdelhameed, S Abeling, K Abicht, NJ Abidi, SH Aboelela, M Aboulhorma, A Abramowicz, H Abreu, H Abulaiti, Y Acharya, BS Ackermann, A Bourdarios, C Adam Adamczyk, L Addepalli, SV Addison, MJ Adelman, J Adiguzel, A Adye, T Affolder, AA https://orcid.org/0000-0002-9058-7217 Afik, Y Agaras, MN Aggarwal, A Agheorghiesei, C Ahmadov, F Ahuja, S Ai, X Aielli, G Aikot, A Tamlihat, M Ait Aitbenchikh, B Akbiyik, M Åkesson, TPA Akimov, AV Akiyama, D Akolkar, NN Aktas, S Khoury, K Al Alberghi, GL Albert, J Albicocco, P Albouy, GL Alderweireldt, S Alegria, ZL Aleksa, M Aleksandrov, IN Alexa, C Alexopoulos, T Alfonsi, F Algren, M Alhroob, M Ali, B Ali, HMJ Ali, S Alibocus, SW Aliev, M Alimonti, G Alkakhi, W Allaire, C Allbrooke, BMM Allen, JS Allen, JF Flores, CA Allendes Allport, PP Aloisio, A Alonso, F Alpigiani, C Alsolami, ZMK Estevez, M Alvarez Fernandez, A Alvarez Cardoso, M Alves Alviggi, MG Aly, M Coutinho, Y Amaral Ambler, A Amelung, C Amerl, M Ames, CG Amidei, D Amini, B Amirie, K Santos, SP Amor Dos Amos, KR Amperiadou, D An, S Ananiev, V Anastopoulos, C Andeen, T Anders, JK Anderson, AC Andrean, SY Andreazza, A Angelidakis, S Angerami, A Anisenkov, AV Annovi, A Antel, C Antipov, E https://escholarship.org/uc/item/2tf9s4rb A measurement of the ratio of the branching fractions, Rτ/e = B(W → τν)/B(W → eν), is performed using a sample of W bosons originating from top-quark decays to final states containing τ-leptons or electrons. This measurement uses pp collisions at s$$ \sqrt{s} $$ = 13 TeV, collected by the ATLAS experiment at the Large Hadron Collider during Run 2, corresponding to an integrated luminosity of 140 fb−1.

Largely put in place by the Securities and Exchange Commission in 1982, the principles underlying the system have failed to keep pace with shifts in the market and dramatic changes in technology. The system requires a paradigm shift and fundamental alterations in the principles underlying the approach to disclosure. The shift must include the integration of comparative data, the expansion of the categories subject to mandatory disclosure, and the disaggregation of financial statements.

The data sample was recorded in 2015 and 2018, amounting to an integrated luminosity of 1.9  nb^{-1}. Events with exactly one electron and one muon and at least two jets are selected. Top-quark pair production is measured with an observed (expected) significance of 5.0 (4.1) standard deviations. The measured top-quark pair production cross section is σ_{tt[over ¯]}=3.6 _{-0.9}^{+1.0}(stat) _{-0.5}^{+0.8}(syst)  μb, with a total relative uncertainty of 31%, and is consistent with theoretical predictions using a range of different nuclear parton distribution functions. The observation of this process consolidates the evidence of the existence of all quark flavors in the preequilibrium stage of the quark-gluon plasma at very high energy densities, similar to the conditions present in the early Universe. https://escholarship.org/uc/item/1b95j172 Wed, 23 Apr 2025 00:00:00 +0000 Aad, G Aakvaag, E Abbott, B Abdelhameed, S Abeling, K Abicht, NJ Abidi, SH Aboelela, M Aboulhorma, A Abramowicz, H Abulaiti, Y Acharya, BS Ackermann, A Bourdarios, C Adam Adamczyk, L Addepalli, SV Addison, MJ Adelman, J Adiguzel, A Adye, T Affolder, AA https://orcid.org/0000-0002-9058-7217 Afik, Y Agaras, MN Aggarwal, A Agheorghiesei, C Ahmadov, F Ahuja, S Ai, X Aielli, G Aikot, A Tamlihat, M Ait Aitbenchikh, B Akbiyik, M Åkesson, TPA Akimov, AV Akiyama, D Akolkar, NN Aktas, S Al Khoury, K Alberghi, GL Albert, J Albicocco, P Albouy, GL Alderweireldt, S Alegria, ZL Aleksa, M Aleksandrov, IN Alexa, C Alexopoulos, T Alfonsi, F Algren, M Alhroob, M Ali, B Ali, HMJ Ali, S Alibocus, SW Aliev, M Alimonti, G Alkakhi, W Allaire, C Allbrooke, BMM Allen, JS Allen, JF Flores, CA Allendes Allport, PP Aloisio, A Alonso, F Alpigiani, C Alsolami, ZMK Fernandez, A Alvarez Cardoso, M Alves Alviggi, MG Aly, M Coutinho, Y Amaral Ambler, A Amelung, C Amerl, M Ames, CG Amidei, D Amini, B Amirie, K Dos Santos, SP Amor Amos, KR Amperiadou, D An, S Ananiev, V Anastopoulos, C Andeen, T Anders, JK Anderson, AC Andreazza, A Angelidakis, S Angerami, A Anisenkov, AV Annovi, A Antel, C Antipov, E Antonelli, M Anulli, F Aoki, M https://escholarship.org/uc/item/0hh500gq The Lund jet plane (LJP) is measured for the first time in tt¯$$t\bar{t}$$ events, using 140&nbsp;fb-1$$\textrm{fb}^{-1}$$ of s=13$$\sqrt{s} = 13$$&nbsp;TeV pp collision data collected with the ATLAS detector at the LHC.

The continued success of the sustainable finance movement will depend on issuers’ motivations to engage in sustainable finance. This essay investigates the justifications for sustainable finance through a hand-collected dataset of disclosures made by green, social, and sustainability bond issuers. Review of these disclosures reveals that material legal, physical, and regulatory risks sometimes impact these issuers, but that these risks are not identified as motivations for engagement in sustainable finance. Instead, issuers appear to be motivated by shareholder pressures and a desire to enhance the green, socially engaged, or sustainable nature of their corporate brand. https://escholarship.org/uc/item/8767t42k Tue, 15 Apr 2025 00:00:00 +0000 Rose, Paul https://escholarship.org/uc/item/54j836d0 <p>This article addresses an unexplored problem in the externalities literature: the present value of future<em> </em>externalities.

These ambitious mandates, core to the EU’s European Green Deal, impose significant environmental and human rights obligations not only on EU companies but also on thousands of non-EU firms—including US companies—with operations or business ties within the bloc. This article explores the implications of these directives for US firms and policymakers, emphasizing their extraterritorial scope and normative ambition. Unlike US law, which is mired in debates over financial materiality and limited by anti-regulatory sentiment and anti-majoritarian structural constraints, the EU directives adopt sustainability as a stand-alone legal goal. These directives position the EU as a de facto global ESG standard-setter, displacing the influence of US corporate governance-based reforms.

Settled law allows corporations and institutional investors to take into account risk factors like climate change and may require them to consider those risks when they are directly material, as climate change is for many industries. If anything, the corporate response to climate change has been too tepid, and the pace of climate change and its corresponding harm is outrunning efforts to constrain it.</p><p>No simple answer exists to addressing the dangers this Orwellian manipulation creates. But identifying that behavior and holding political elites responsible for a basic acceptance of fact and for consistently applying their stated principles is a necessary start.</p> https://escholarship.org/uc/item/3q86m244 Tue, 15 Apr 2025 00:00:00 +0000 Strine, Jr., Leo E. https://escholarship.org/uc/item/3386b28c Directors’ fiduciary duties in Canada include an obligation to identify and oversee management of the company’s climate-related risks and opportunities.

Part of this delay stems from a perceived “ESG backlash,” which has contributed to the SEC’s reluctance to require industry to disclose ESG practices. The regulatory landscape has now shifted, with the SEC proposing two ESG-centric rules—the ESG Fund Disclosure Rule and the ESG Names Rule.</p><p> <em> </em> </p> Both rules have garnered numerous comments from academics, industry, investors, NGOs, and political actors.

ATLAS has measured production of dijet and multijet final states in ultraperipheral collisions at using a dataset recorded in 2018 with an integrated luminosity of . Photonuclear final states are selected by requiring a rapidity gap in the photon direction; this selects events where one of the outgoing nuclei remains intact.

Such an increase will create a very challenging environment in which to perform charged particle trajectory reconstruction, a task crucial for the success of the ATLAS physics program, and will exceed the capabilities of the current ATLAS Inner Detector (ID). A new all-silicon Inner Tracker (ITk) will replace the current ID in time for the start of the HL-LHC. To ensure successful use of the ITk capabilities in Run 4 and beyond, the ATLAS tracking software has been successfully adapted to achieve state-of-the-art track reconstruction in challenging high-luminosity conditions with the ITk detector.

Such financial obligations may produce a criminalization of poverty, where later court involvement results not from crime but from an inability to meet the financial burdens of the legal process. We test this hypothesis using a randomized controlled trial of court-related fee relief for misdemeanor defendants in Oklahoma County, Oklahoma. We find that relief from fees does not affect new criminal charges, convictions, or jail bookings after 12 months. However, control respondents were subject to debt collection efforts at significantly higher rates that involved new warrants, additional court debt, tax refund garnishment, and referral to a private debt collector. Despite significant efforts at debt collection among those in the control group, payments to the court totaled less than 5 percent of outstanding debt.

In the 2020 election, public benefits recipients comprised over 20% of the voting-eligible population but only 12% of voters. To the extent that benefits recipients are more supportive of generous welfare policy than nonrecipients and more familiar with administrative burdens programs impose, this underrepresentation may obscure popular... https://escholarship.org/uc/item/5491m66c Wed, 12 Feb 2025 00:00:00 +0000 Chizeck, Seth Fong, Kelley Goldstein, Rebecca White, Ariel R https://escholarship.org/uc/item/1s07n3w7 Many topics social scientists study are sensitive in nature. Although we know some people may be reluctant to respond to sensitive questions in surveys, we know less about how such questions could influence responses to other questions appearing later in a survey. In this study, we use the Trump administration’s proposal to include a citizenship question on the 2020 Census to demonstrate how such spillover effects can undermine important survey-based estimates. Using a large survey experiment (n p 9,035 respondents), we find that asking about citizenship status significantly increases the percentage of questions skipped and makes respondents less likely to report that members of their household are Hispanic. Not only does this demonstrate that sensitive questions can have important downstream effects on survey responses, but our results also speak to an important public policy debate that will likely arise in the future. https://escholarship.org/uc/item/1s07n3w7 Wed, 12 Feb 2025 00:00:00 +0000 Baum, Matthew A Dietrich, Bryce J Goldstein, Rebecca Sen, Maya https://escholarship.org/uc/item/9w37d7s7 High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.02 and 5.44&nbsp;TeV, respectively, using the ATLAS detector at the LHC. All observables show distinct features in ultracentral collisions, which are explained by a suppression of the geometrical component as the overlap area reaches its maximum. These results demonstrate a new technique to separate geometrical and intrinsic fluctuations, providing constraints on initial conditions and properties of the quark-gluon plasma, such as... https://escholarship.org/uc/item/9w37d7s7 Tue, 11 Feb 2025 00:00:00 +0000 Aad, G Aakvaag, E Abbott, B Abdelhameed, S Abeling, K Abicht, NJ Abidi, SH Aboelela, M Aboulhorma, A Abramowicz, H Abreu, H Abulaiti, Y Acharya, BS Ackermann, A Bourdarios, C Adam Adamczyk, L Addepalli, SV Addison, MJ Adelman, J Adiguzel, A Adye, T Affolder, AA https://orcid.org/0000-0002-9058-7217 Afik, Y Agaras, MN Agarwala, J Aggarwal, A Agheorghiesei, C Ahmadov, F Ahmed, WS Ahuja, S Ai, X Aielli, G Aikot, A Tamlihat, M Ait Aitbenchikh, B Akbiyik, M Åkesson, TPA Akimov, AV Akiyama, D Akolkar, NN Aktas, S Al Khoury, K Alberghi, GL Albert, J Albicocco, P Albouy, GL Alderweireldt, S Alegria, ZL Aleksa, M Aleksandrov, IN Alexa, C Alexopoulos, T Alfonsi, F Algren, M Alhroob, M Ali, B Ali, HMJ Ali, S Alibocus, SW Aliev, M Alimonti, G Alkakhi, W Allaire, C Allbrooke, BMM Allen, JF Flores, CA Allendes Allport, PP Aloisio, A Alonso, F Alpigiani, C Alsolami, ZMK Estevez, M Alvarez Fernandez, A Alvarez Cardoso, M Alves Alviggi, MG Aly, M Coutinho, Y Amaral Ambler, A Amelung, C Amerl, M Ames, CG Amidei, D Amini, B Amirie, KJ Dos Santos, SP Amor Amos, KR An, S Ananiev, V Anastopoulos, C Andeen, T Anders, JK Anderson, AC Andrean, SY Andreazza, A Angelidakis, S Angerami, A Anisenkov, AV Annovi, A Antel, C Antipov, E https://escholarship.org/uc/item/52b9t805 A search for a light charged Higgs boson produced in decays of the top quark, t→H±b$$t \rightarrow H^{\pm } b$$ with H±→cs$$H^{\pm } \rightarrow cs$$, is presented.

Seamless integration of Google cloud resources into the worldwide ATLAS distributed computing infrastructure was achieved at large scale and for an extended period of time, and hence cloud resources are shown to be an effective mechanism to provide additional, flexible computing capacity to ATLAS. For the first time a total cost of ownership analysis has been performed, to identify the dominant cost drivers and explore effective mechanisms for cost control.

This method relies on the assumption that the tree-level Higgs-top Yukawa coupling strength is the same for on-shell and off-shell Higgs boson production processes, thereby avoiding any assumptions about the relationship between on-shell and off-shell gluon fusion Higgs production rates, which were central to previous measurements. The result is based on up to 140 fb−1 of proton–proton collisions at a centre-of-mass energy of s = 13 TeV collected with the ATLAS detector at the Large Hadron Collider. The observed (expected) 95% confidence level upper limit on Γ H is 450 MeV (75 MeV).

All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins. In this analysis, a machine learning method called omnifold is used to produce a simultaneous measurement of twenty-four Z+jets observables using 139  fb^{-1} of proton-proton collisions at sqrt[s]=13  TeV collected with the ATLAS detector. Unlike any previous fiducial differential cross-section measurement, this result is presented unbinned as a dataset of particle-level events, allowing for flexible reuse in a variety of contexts and for new observables to be constructed from... https://escholarship.org/uc/item/051428zd Tue, 4 Feb 2025 00:00:00 +0000 Aad, G Aakvaag, E Abbott, B Abdelhameed, S Abeling, K Abicht, NJ Abidi, SH Aboelela, M Aboulhorma, A Abramowicz, H Abreu, H Abulaiti, Y Acharya, BS Ackermann, A Bourdarios, C Adam Adamczyk, L Addepalli, SV Addison, MJ Adelman, J Adiguzel, A Adye, T Affolder, AA https://orcid.org/0000-0002-9058-7217 Afik, Y Agaras, MN Agarwala, J Aggarwal, A Agheorghiesei, C Ahmadov, F Ahmed, WS Ahuja, S Ai, X Aielli, G Aikot, A Tamlihat, M Ait Aitbenchikh, B Akbiyik, M Åkesson, TPA Akimov, AV Akiyama, D Akolkar, NN Aktas, S Al Khoury, K Alberghi, GL Albert, J Albicocco, P Albouy, GL Alderweireldt, S Alegria, ZL Aleksa, M Aleksandrov, IN Alexa, C Alexopoulos, T Alfonsi, F Algren, M Alhroob, M Ali, B Ali, HMJ Ali, S Alibocus, SW Aliev, M Alimonti, G Alkakhi, W Allaire, C Allbrooke, BMM Allen, JF Flores, CA Allendes Allport, PP Aloisio, A Alonso, F Alpigiani, C Alsolami, ZMK Estevez, M Alvarez Fernandez, A Alvarez Cardoso, M Alves Alviggi, MG Aly, M Coutinho, Y Amaral Ambler, A Amelung, C Amerl, M Ames, CG Amidei, D Amirie, KJ Dos Santos, SP Amor Amos, KR An, S Ananiev, V Anastopoulos, C Andeen, T Anders, JK Anderson, AC Andrean, SY Andreazza, A Angelidakis, S Angerami, A Anisenkov, AV Annovi, A Antel, C Antipov, E Antonelli, M https://escholarship.org/uc/item/9x1937cn Front Matter v5 iss1 https://escholarship.org/uc/item/9x1937cn Fri, 31 Jan 2025 00:00:00 +0000 Editors, JLPE https://escholarship.org/uc/item/8pc158nm Review of Ruth Dukes and Wolfgang Streeck, Democracy at Work: Contract, Status and Post-Industrial Justice (Polity Press, 2023) https://escholarship.org/uc/item/8pc158nm Fri, 31 Jan 2025 00:00:00 +0000 Bogoeski, Vladimir https://escholarship.org/uc/item/5md2708c Review of Julia Calvert, The Politics of Investment Treaties in Latin America (Oxford University Press, 2022) https://escholarship.org/uc/item/5md2708c Fri, 31 Jan 2025 00:00:00 +0000 Lopez, Clara https://escholarship.org/uc/item/5784v5f1 <p>The Biden administration’s initiative to modernize regulatory review, while attempting to incorporate various criticisms of cost-benefit analysis (CBA), was hobbled by an insufficient theoretical analysis. Specifically, the administration failed to address its implicit naturalization of the economic subject, under which subjects and their preferences are regarded as exogenous givens. The justification for CBA is that it can use information regarding individual “willingness to pay” (WTP) or “willingness to accept” (WTA) to discern these preferences, and thereby create efficient policy. But if the naturalized subject is fictional, then there is nothing to discern. Subjects and their preferences are not waiting to be found; rather, they are endogenously shaped. Recognition of this endogeneity would allow for preferences, or values, constituted through democratic spaces to be no less salient to policy than those ostensibly exogenous to the market.&nbsp;Further, it would allow for... https://escholarship.org/uc/item/5784v5f1 Fri, 31 Jan 2025 00:00:00 +0000 Silverman, Mark https://escholarship.org/uc/item/3tm5v8q5 <p>The fundamental legal, normative, and politico-economic assumptions underpinning both competition law and administrative governance are in a period of considerable flux (Harris and Varellas 2020, 3; Britton-Purdy et al. 2020, 1801-02; Khan 2019; Rahman 2018). Past calls for a renewed economic analysis of law are striking a chord with present scholars. In this issue of the <em>Journal of Law and Political Economy</em>, we commence a specially edited series of articles focused on the value, shortcomings, and potential improvement of quantitative analysis in competition law and regulatory decision-making. This multi-year project aims to provide guidance and insight to advocates, judges, and regulators on the proper nature and scope of quantitative methods in several important areas of law and policy.</p> https://escholarship.org/uc/item/3tm5v8q5 Fri, 31 Jan 2025 00:00:00 +0000 Pasquale, Frank Varellas, James J https://escholarship.org/uc/item/1wj7x32x Review of Andrew Schrank, The Economic Sociology of Development (Polity Press, 2023) https://escholarship.org/uc/item/1wj7x32x Fri, 31 Jan 2025 00:00:00 +0000 Mouallem, Pedro https://escholarship.org/uc/item/74b905p6 In this essay, we detail the fundamental reasons for antitrust policy’s right turn toward the consumer welfare theory and against antitrust enforcement in the 1970s. Two recent articles raise questions as to the cause of this turn, with one article arguing that big business capture facilitated the right turn, while another touts a consensus around science-based economics. We argue that while the capture theory is more persuasive, power dynamics between heterogeneous business alliances shifted due to changes in the economy that eroded the incomes of the wealthiest; reductions in antitrust enforcement was one means of restoring that lost income. This essay details that economic history in support of a more nuanced capture theory. https://escholarship.org/uc/item/74b905p6 Thu, 30 Jan 2025 00:00:00 +0000 Bush, Darren Glick, Mark Lozada, Gabriel A. https://escholarship.org/uc/item/41d8x6np <p>There is an emerging belief that antitrust has failed marginalized populations. For example, exclusionary practices have helped to produce banking and food deserts in low-income communities, though antitrust has seldom intervened. But is this a problem of antitrust law? In fact, another claim is that antitrust <em>law </em>is just fine as opposed to how federal agencies <em>enforce </em>antitrust. Since agencies must decide which cases to bring, they should perhaps pay better attention to marginalized communities or draft complaints to emphasize their unique injuries. This topic is especially salient, given the ongoing debate about whether the consumer welfare standard is able to promote competition in modern markets. In essence, the root of why antitrust has yet to meet its potential of serving marginalized communities may lie with the law and its interpretation or, alternatively, people and organizations enforcing it.</p> https://escholarship.org/uc/item/41d8x6np Thu, 30 Jan 2025 00:00:00 +0000 Day, Gregory https://escholarship.org/uc/item/3qn3f1c6 In March 1923, a group of prominent political economists and tax law experts gathered in Geneva, Switzerland to discuss the post–World War I framework for a new international tax regime. Commissioned by the League of Nations, these experts produced a comprehensive report that gradually became the intellectual foundation of the modern international tax regime. Relying on archival materials and other primary sources, this article contends that the US expert Edwin R. A. Seligman played a vital role in revising the report. While scholars have noted Seligman’s influence over US tax law and policy, his pivotal role in drafting the 1923 report has only recently been acknowledged. This article builds on this recent scholarship by investigating how Seligman’s background, experiences, and ideas—particularly his analysis and advocacy of the concept of “ability to pay” and “economic allegiance”—shaped the 1923 Report, and hence the subsequent development of the modern international tax regime. https://escholarship.org/uc/item/3qn3f1c6 Thu, 30 Jan 2025 00:00:00 +0000 Mehrotra, Ajay https://escholarship.org/uc/item/0m10m2r6 <p>In Ontario’s far north, settler state authorities and extractive firms are engaged in coordinated tactics to gain ground amid a polarization in the positions of Indigenous leadership. Alongside a surging resistance, we also witness a resigned acceptance of critical minerals mining by some First Nations. Drawing on years of community-engaged research, I detail here the contemporary tactics of “infrastructural (dis)entitlement:” in this dynamic, infrastructural needs are both denied and fulfilled to differential effect. Infrastructural <em>disentitlement</em> is passive; it is not necessarily deliberate, nor is it politically or institutionally organized. But infrastructural <em>entitlement</em> is strategic and aggressive: Indigenous prosperity and inclusion are key elements of the contemporary liberal justification for critical minerals extraction. From this, a pattern emerges of places toward which resources are flowing and places out of which they are draining. The chronic... https://escholarship.org/uc/item/0m10m2r6 Thu, 30 Jan 2025 00:00:00 +0000 Scott, Dayna Nadine https://escholarship.org/uc/item/15p0c2gv US courts regularly assess fines, fees, and costs against criminal defendants. Court-related debt can cause continuing court involvement and incarceration, not because of new crimes, but because of unpaid financial obligations. We conducted an experiment with 606 people found guilty of misdemeanors in Oklahoma County, Oklahoma. Study participants were randomly selected to receive relief from all current and prior fines and fees assessed for criminal charges in the county. Fee relief reduced jail bookings 21 mo after randomization and the effect persisted over 44 mo of follow-up. Although fee relief reduced incarceration, financial sanctions had no effect on indicators of lawbreaking. Instead, the control group (who obtained no relief from fines and fees) were rearrested at significantly higher rates because of open arrest warrants for nonpayment. These results indicate the long-term and criminalizing effects of legal debt, supporting claims that financial sanctions disproportionately... https://escholarship.org/uc/item/15p0c2gv Wed, 29 Jan 2025 00:00:00 +0000 Bing, Lindsay Goldstein, Rebecca Ho, Helen Pager, Devah Western, Bruce https://escholarship.org/uc/item/6t69p853 A combination of searches for singly and doubly charged Higgs bosons, H ± and H ± ± , produced via vector-boson fusion is performed using 140 fb−1 of proton–proton collisions at a centre-of-mass energy of 13 TeV, collected with the ATLAS detector during Run 2 of the Large Hadron Collider. Searches targeting decays to massive vector bosons in leptonic final states (electrons or muons) are considered. New constraints are reported on the production cross-section times branching fraction for charged Higgs boson masses between 200 GeV and 3000 GeV. The results are interpreted in the context of the Georgi-Machacek model for which the most stringent constraints to date are set for the masses considered in the combination. https://escholarship.org/uc/item/6t69p853 Wed, 4 Dec 2024 00:00:00 +0000 Aad, G Aakvaag, E Abbott, B Abdelhameed, S Abeling, K Abicht, NJ Abidi, SH Aboelela, M Aboulhorma, A Abramowicz, H Abreu, H Abulaiti, Y Acharya, BS Ackermann, A Bourdarios, C Adam Adamczyk, L Addepalli, SV Addison, MJ Adelman, J Adiguzel, A Adye, T Affolder, AA https://orcid.org/0000-0002-9058-7217 Afik, Y Agaras, MN Agarwala, J Aggarwal, A Agheorghiesei, C Ahmadov, F Ahmed, WS Ahuja, S Ai, X Aielli, G Aikot, A Tamlihat, M Ait Aitbenchikh, B Akbiyik, M Åkesson, TPA Akimov, AV Akiyama, D Akolkar, NN Aktas, S Al Khoury, K Alberghi, GL Albert, J Albicocco, P Albouy, GL Alderweireldt, S Alegria, ZL Aleksa, M Aleksandrov, IN Alexa, C Alexopoulos, T Alfonsi, F Algren, M Alhroob, M Ali, B Ali, HMJ Ali, S Alibocus, SW Aliev, M Alimonti, G Alkakhi, W Allaire, C Allbrooke, BMM Allen, JS Allen, JF Flores, CA Allendes Allport, PP Aloisio, A Alonso, F Alpigiani, C Alsolami, ZMK Estevez, M Alvarez Fernandez, A Alvarez Cardoso, M Alves Alviggi, MG Aly, M Coutinho, Y Amaral Ambler, A Amelung, C Amerl, M Ames, CG Amidei, D Amini, B Amirie, KJ Dos Santos, SP Amor Amos, KR Amperiadou, D An, S Ananiev, V Anastopoulos, C Andeen, T Anders, JK Anderson, AC Andrean, SY Andreazza, A Angelidakis, S Angerami, A Anisenkov, AV Annovi, A https://escholarship.org/uc/item/1wf4j6dp A search for heavy right-handed Majorana neutrinos is performed with the ATLAS detector at the CERN Large Hadron Collider, using the of proton–proton collision data at collected during Run 2. This search targets production, in which both top quarks decay into a bottom quark and a boson, where one of the bosons decays hadronically and the other decays into an electron or muon and a heavy neutral lepton. The heavy neutral lepton is identified through a decay into an electron or muon and another boson, resulting in a pair of same-charge same-flavor leptons in the final state. This paper presents the first search for heavy neutral leptons in the mass range of 15–75&nbsp;GeV using events. No significant excess is observed over the background expectation, and upper limits are placed on the signal cross sections. Assuming a benchmark scenario of the phenomenological type-I seesaw model, these cross section limits are then translated into upper limits on the mixing parameters of... https://escholarship.org/uc/item/1wf4j6dp Wed, 4 Dec 2024 00:00:00 +0000 Aad, G Aakvaag, E Abbott, B Abdelhameed, S Abeling, K Abicht, NJ Abidi, SH Aboelela, M Aboulhorma, A Abramowicz, H Abreu, H Abulaiti, Y Acharya, BS Ackermann, A Bourdarios, C Adam Adamczyk, L Addepalli, SV Addison, MJ Adelman, J Adiguzel, A Adye, T Affolder, AA https://orcid.org/0000-0002-9058-7217 Afik, Y Agaras, MN Agarwala, J Aggarwal, A Agheorghiesei, C Ahmadov, F Ahmed, WS Ahuja, S Ai, X Aielli, G Aikot, A Tamlihat, M Ait Aitbenchikh, B Akbiyik, M Åkesson, TPA Akimov, AV Akiyama, D Akolkar, NN Aktas, S Al Khoury, K Alberghi, GL Albert, J Albicocco, P Albouy, GL Alderweireldt, S Alegria, ZL Aleksa, M Aleksandrov, IN Alexa, C Alexopoulos, T Alfonsi, F Algren, M Alhroob, M Ali, B Ali, HMJ Ali, S Alibocus, SW Aliev, M Alimonti, G Alkakhi, W Allaire, C Allbrooke, BMM Allen, JF Flores, CA Allendes Allport, PP Aloisio, A Alonso, F Alpigiani, C Alsolami, ZMK Estevez, M Alvarez Fernandez, A Alvarez Cardoso, M Alves Alviggi, MG Aly, M Coutinho, Y Amaral Ambler, A Amelung, C Amerl, M Ames, CG Amidei, D Amirie, KJ Dos Santos, SP Amor Amos, KR An, S Ananiev, V Anastopoulos, C Andeen, T Anders, JK Anderson, AC Andrean, SY Andreazza, A Angelidakis, S Angerami, A Anisenkov, AV Annovi, A Antel, C Antipov, E Antonelli, M
