Pier Paolo Pasolini's work transcends the boundaries of the Italian peninsula. His analysis on Italian folk and subproletariat culture extends as far as considering similar situations in the so-called Third World, which Pasolini identifies with the Mediterranean area. This article provides a detailed mapping of Pasolini's peculiar Mediterranean geography, a mobile, unstable geography, defined in this article through a careful reading of his films, novels, essays, and letters. Beginning with a comparison between *Uccellacci e uccellini* (1966) and its original screenplay, the author shows that the boundaries of Pasolini's Mediterranean - a space conceived as irrational, barbarian and primitive - are constantly de-territorialized and re-territorialized. The article focuses in particular on Pasolini's movies dedicated to ancient Greece, *Edipus Rex* (1967) and *Medea* (1969), both shot in Mediterranean countries like Morocco and Turkey and yet visually contaminated and re-invented through the use of Italian, African and Far Eastern elements. Pasolini's uniquely idealized Mediterranean becomes a multi-layered laboratory for his critique of the model of capitalistic development, which Pasolini believed was destroying all particular cultures, and a mental space to elaborate his own form of anticolonialist thought.

© Published by the American Physical Society. Measurements of normalized differential cross sections for top-quark pair production are presented as a function of the top-quark transverse momentum, and of the mass, transverse momentum, and rapidity of the tt¯ system, in proton-proton collisions at a center-of-mass energy of s=7TeV. The data set corresponds to an integrated luminosity of 4.6fb-1, recorded in 2011 with the ATLAS detector at the CERN Large Hadron Collider. Events are selected in the lepton+jets channel, requiring exactly one lepton and at least four jets with at least one of the jets tagged as originating from a b-quark. The measured spectra are corrected for detector efficiency and resolution effects and are compared to several Monte Carlo simulations and theory calculations. The results are in fair agreement with the predictions in a wide kinematic range. Nevertheless, data distributions are softer than predicted for higher values of the mass of the tt¯ system and of the top-quark transverse momentum. The measurements can also discriminate among different sets of parton distribution functions.

This Letter presents a search for the Standard Model Higgs boson in the decay channel H→ZZ (*) →ℓ + ℓ - ℓ '+ ℓ '- , where ℓ, ℓ ' =e or μ, using proton-proton collisions at √s=7 TeV recorded with the ATLAS detector and corresponding to an integrated luminosity of 4.8 fb -1 . The four-lepton invariant mass distribution is compared with Standard Model background expectations to derive upper limits on the cross section of a Standard Model Higgs boson with a mass between 110 GeV and 600 GeV. The mass ranges 134-156 GeV, 182-233 GeV, 256-265 GeV and 268-415 GeV are excluded at the 95% confidence level. The largest upward deviations from the background-only hypothesis are observed for Higgs boson masses of 125 GeV, 244 GeV and 500 GeV with local significances of 2.1, 2.2 and 2.1 standard deviations, respectively. Once the look-elsewhere effect is considered, none of these excesses are significant. © 2012 CERN.

A search is presented for a narrow resonance decaying to a pair of Z bosons using data corresponding to 1.02fb -1 of integrated luminosity collected by the ATLAS experiment from pp collisions at √s=7TeV. Events containing either four charged leptons (ℓℓℓℓ) or two charged leptons and two jets (ℓℓjj) are analyzed and found to be consistent with the Standard Model background expectation. Lower limits on a resonance mass are set using the Randall-Sundrum (RS1) graviton model as a benchmark. Using both ℓℓℓℓ and ℓℓjj events, an RS1 graviton with k/m-pl=0.1 and mass between 325 and 845 GeV is excluded at 95% confidence level. In addition, the ℓℓℓℓ events are used to set a model-independent fiducial cross section limit of σ fid (pp→X→ZZ)<0.92pb at 95% confidence level for any new sources of ZZ production with m ZZ greater than 300 GeV. © 2012 CERN.

Correlations between the elliptic or triangular flow coefficients vm (m=2 or 3) and other flow harmonics vn (n=2 to 5) are measured using sNN=2.76 TeV Pb+Pb collision data collected in 2010 by the ATLAS experiment at the LHC, corresponding to an integrated luminosity of 7 μb-1. The vm-vn correlations are measured in midrapidity as a function of centrality, and, for events within the same centrality interval, as a function of event ellipticity or triangularity defined in a forward rapidity region. For events within the same centrality interval, v3 is found to be anticorrelated with v2 and this anticorrelation is consistent with similar anticorrelations between the corresponding eccentricities, ε2 and ε3. However, it is observed that v4 increases strongly with v2, and v5 increases strongly with both v2 and v3. The trend and strength of the vm-vn correlations for n=4 and 5 are found to disagree with εm-εn correlations predicted by initial-geometry models. Instead, these correlations are found to be consistent with the combined effects of a linear contribution to vn and a nonlinear term that is a function of v22 or of v2v3, as predicted by hydrodynamic models. A simple two-component fit is used to separate these two contributions. The extracted linear and nonlinear contributions to v4 and v5 are found to be consistent with previously measured event-plane correlations.

A blind analysis searching for the decay Bs0→μ+μ- has been performed using proton-proton collisions at a centre-of-mass energy of 7 TeV recorded with the ATLAS detector at the LHC. With an integrated luminosity of 2.4 fb-1 no excess of events over the background expectation is found and an upper limit is set on the branching fraction BR(Bs0→μ+μ-)<2.2(1.9)×10-8 at 95% (90%) confidence level. © 2012 CERN.

Corrections to two figures, one table and the corresponding numbers in the text are noted for the paper. Systematic uncertainties arising from the comparison of the nominal tt¯tt¯ simulation with alternative samples generated with Sherpa and with MadGraph5_aMC@NLO+Herwig7 were not applied when deriving limits on the top-quark Yukawa coupling, Higgs oblique parameter and EFT operators. This affects Figs. 8 and 9, and Table 8. (Figure presented.) (Figure presented.) (Table presented.) Two-dimensional negative log-likelihood contours for |κtcos(α)| versus |κtsin(α)| at 68% and 95%, where κt is the top-Higgs Yukawa coupling strength parameter and α is the mixing angle between the CP-even and CP-odd components. The gradient-shaded area represents the observed likelihood value as a function of κt and α. Both the tt¯tt¯ signal and tt¯H background yields in each fitted bin are parameterised as a function of κt and α. The blue cross shows the SM expectation, while the black cross shows the best fit value The negative log-likelihood values as a function of the Higgs oblique parameter H^. The solid line represents the observed likelihood while the dashed line corresponds to the expected one. The dashed region shows the non-unitary regime Expected and observed 95% CL intervals on EFT coupling parameters assuming one EFT parameter variation in the fit Operators Expected Ci/Λ2 [TeV -2] Observed Ci/Λ2 [TeV -2] OQQ1 [-2.5,3.2] [-4.0,4.5] OQt1 [-2.6,2.1] [-3.8,3.4] Ott1 [-1.2,1.4] [-1.9,2.1] OQt8 [-4.3,5.1] [-6.9,7.6] The changes in the text are noted for Sects. 9.1, 9.2 and 10. In Sect. 9.1, for the case when the tt¯tt¯ and tt¯H yields in each bin of the GNN distribution are parameterised as a function of κt and α and fixing the top-quark Yukawa coupling to be CP-even only, the observed limit is |κt|<1.9 instead of |κt|<1.8. If the tt¯H background yields are not parametrised, whilst the normalisation of the tt¯H background is treated as a free parameter of the fit, the observed (expected) limit is |κt|<2.3 (1.9) instead of |κt|<2.2 (1.8). In Sect. 9.2, the upper limits on the absolute values of the coefficients (|Ci/Λ2|) of OQQ1, OQt1, Ott1 and OQt8 assuming only the linear terms are 6.6, 4.0, 2.8 and 10.8 TeV -2, respectively, at 95% CL instead of 5.3, 3.3, 2.4 and 8.8 TeV -2. In Sect. 9.2, the observed (expected) upper limit on the H^ parameter is 0.23 (0.11) at 95% CL instead of 0.20 (0.12). The published expected upper limit of 0.12 was a mistake in the text and should have been 0.1 corresponding to the likelihood scan in Fig. 9. The observed limit is weaker than the largest value of this parameter equal to 0.2 that preserves unitarity in the perturbative theory. In Sect. 10, assuming a pure CP-even coupling (α=0), the observed upper limit on |κt|=|yt/ytSM| at 95% CL is 1.9 instead of 1.8. Assuming one operator taking effect at a time, the observed constraints on the coefficients (Ci/Λ2) of OQQ1, OQt1, Ott1 and OQt8 are [-4.0,4.5], [-3.8,3.4], [-1.9,2.1] and [-6.9,7.6] TeV -2, respectively. An observed upper limit at 95% CL of 0.23 is obtained for the Higgs oblique parameter that is weaker than the largest value that preserves unitarity in the perturbative theory.

© CERN for the benefit of the ATLAS collaboration. Ameasurement is presented of the φ×BR(φ → K

^{+}K^{−}) production cross section at √s = 7 TeV using pp collision data corresponding to an integrated luminosity of 383 μb^{-1}, collected with theATLAS experiment at the LHC. Selection of φ(1020) mesons is based on the identification of charged kaons by their energy loss in the pixel detector. The differential cross section ismeasured as a function of the transverse momentum, pT,φ , and rapidity, yφ, of the φ(1020) meson in the fiducial region 500< pT,φ <1200MeV, |yφ| < 0.8, kaon pT,K > 230 MeV and kaon momentum pK < 800 MeV. The integrated φ(1020)-meson production cross section in this fiducial range is measured to be σφ×BR(φ → K^{+}K^{−}) = 570 ± 8 (stat) ± 66 (syst) ± 20 (lumi) μb.
