Title: Probing Non-standard Interaction Of Neutrinos With Icecube And Deepcore

Abstract: We consider effects of the Non-Standard Interactions (NSI) on oscillations of the high energy atmospheric neutrinos. The ν μ -oscillograms are constructed and their dependence on the NSI strength parameters Ïμ αβ studied. We computed the zenith angle distributions of the ν μ -events in the presence of NSI in different energy regions. The distributions are confronted with the IceCube-79 (high energy sample) and the DeepCore (low energy sample) data and constraints on the strength parameters |Ïμ μτ |≠6 × 10-3 and |Ïμ μμ - Ïμ ττ | â‰3 × 10-2 (90% C.L.) have been obtained. Future measurements of the zenith angle distributions by DeepCore in several energy bins will allow to improve the bounds by factor 2-3. We discuss the signatures of NSI in the zenith angle and energy distributions of events which allow to discriminate them from the effects of sterile neutrinos. © 2013 SISSA, Trieste, Italy.
