Testing nonstandard neutrino matter interactions in atmospheric neutrino propagation

We study the eects of non-standard interactions on the oscillation pattern of atmospheric neutrinos. We use neutrino oscillograms as our main tool to infer the role of non-standard interactions (NSI) parameters at the probability level in the energy range, E 2 [1; 20] GeV and zenith angle range, cos 2 [ 1; 0]. We compute the event rates for atmospheric neutrino events in presence of NSI parameters in the energy range E2 [1; 10] GeV for two dierent detector congurations - a magnetized iron calorimeter and an unmagnetized liquid
