Non-Standard Interactions (NSI) between neutrinos and matter affect neutrino flavor oscillations.

Due to the high matter density in the core of the Sun, solar neutrinos are well suited to probe these interactions.

Using the 277 kton-yr exposure of Super-Kamiokande to $^{8}$B solar neutrinos, we search for the presence of NSI.

Our data favors the presence of NSI with down quarks at 1.8$\sigma$, and with up quarks at 1.6$\sigma$, with the best-fit effective NSI parameters being ($\epsilon_{11}^{\textrm{d}},\epsilon_{12}^{\textrm{d}}$) = (-3.3, -3.1) for d-quarks and

($\epsilon_{11}^{\textrm{u}},\epsilon_{12}^{\textrm{u}}$) = (-2.5, -3.1) for u-quarks.

After combining with data from the Sudbury Neutrino Observatory and Borexino, the significance increases by 0.1$\sigma$.

    We propose a new strategy to systematically search for new physics processes in particle collisions at the energy frontier. An examination of all possible topologies which give identifiable resonant features in a specific final state leads to a tractable number of "topological models" per final state and gives specific guidance for their discovery. Using one specific final state, jj, as an example, we find that the number of possibilities is reasonable and reveals simple, but as-yet-unexplored, topologies which contain significant discovery potential. We propose analysis techniques and estimate the sensitivity for pp collisions with s=14TeV and L=300 fb-1. © 2014 American Physical Society.
