Interaction Type Distinction for Cascade Events in IceCube — •Anna Steuer and Lutz Köpke for the IceCube collaboration — Universität Mainz

Cascade event signatures in IceCube originate either from a charged current interaction of electron or tau neutrinos or from a neutral current interaction of all neutrino flavors. The former induces an electromagnetic plus a hadronic shower while the latter initiates a hadronic cascade only. In my talk, I will present promising results of a feasibility study investigating whether an experimental distinction between these types is possible in IceCube. The study, using Geant4, Pythia and DIRE software, exploits the delayed photon signal from neutron capture events, which is more pronounced in hadronic showers.
