Bounds on non-standard interactions of neutrinos from IceCube DeepCore data

Abstract

Abstract New physics in neutrino sector can reveal itself via non-standard neutrino in- teractions which can result in modification of the standard picture of neutrino propagation in matter. Experiments with atmospheric neutrinos has been used to probe this scenario. Using publicly available three-year low energy data in IceCube DeepCore we place bounds on the parameters E αβ of non-standard neutrino interactions in propagation. We obtain re- strictive constraints not only for μτ sector but also for flavor changing interactions involving electron neutrinos.
