Abstract

For many years IceCube DeepCore has measured atmospheric neutrino interactions in the optically clear, deep ice at the South Pole. Analysing only three years of data has yielded the most precise measurements of the atmospheric neutrino oscillation parameters above 5 GeV. Measuring oscillations at these high energies, well above the tau-production threshold, and over extremely long baselines, provides strong constraints on new, Beyond Standard Model physics in a region of phase space uniquely accessed with atmospheric neutrinos. Here we report on the most recent searches for non-standard atmospheric neutrino oscillations with IceCube DeepCore.
