Abstract

The neutral-current (NC) nonstandard interactions (NSIs) of neutrinos with fermions can modify the flavor oscillations of atmospheric neutrinos as they propagate through the Earth. We present constraints on the NC-NSI parameters ϵμτ and ϵττ−ϵμμ (one at a time) using a high-purity sample of νμ charged-current atmospheric neutrino events collected by IceCube DeepCore over 7.5 years of live time. These two parameters significantly affect the νμ disappearance channel for which this golden event sample is optimized by IceCube Collaboration. The best fit to this dataset is consistent with no NSI hypothesis, and we place the stringent constraints −0.0094<ϵμτ<0.0079 and −0.031<ϵττ−ϵμμ<0.029 at the 90% confidence level, assuming normal mass ordering.
