Abstract

SeriesInformation ; Journal of cosmology and astroparticle physics 2016(04), 022 (2016). doi:10.1088/1475-7516/2016/04/022 ; Abstract ; We present an improved event-level likelihood formalism for including neutrino telescope data in global fits to new physics. We derive limits on spin-dependent dark matter-proton scattering by employing the new formalism in a re-analysis of data from the 79-string IceCube search for dark matter annihilation in the Sun, including explicit energy information for each event. The new analysis excludes a number of models in the weak-scale minimal supersymmetric standard model (MSSM) for the first time. This work is accompanied by the public release of the 79-string IceCube data, as well as an associated computer code for applying the new likelihood to arbitrary dark matter models. ; Other ; Published by IOP, London
