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

Abstract

New physics in neutrino sector can reveal itself via non-standard neutrino interactions 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 ${\epsilon }_{\alpha \beta }$ of non-standard neutrino interactions in propagation. We obtain restrictive constraints not only for $\mu \tau$ sector but also for flavor changing interactions involving electron neutrinos.
