Event selection studies for the IceCube-Upgrade — •Cristian Jesús Lozano Mariscal and Alexander Kappes for the IceCube collaboration — Institüt für Kernphysik, Westfälische Wilhelms-Universität Münster, Münster

For the planned upgrade of the IceCube neutrino telescope, seven additional strings equipped with new optical modules will be installed in the center of DeepCore, the current low energy IceCube extension. The upgrade will significantly enhance IceCube's low-energy neutrino detection capabilities with the goal of performing precision measurements in atmospheric neutrino oscillation, and improve the calibration of the existing IceCube detector in particular also for the reconstruction of astrophysical high-energy neutrinos. In order to achieve these goals, a crucial pre-requisite is to accurately distinguish between neutrinos and atmospheric muons. This study presents initial studies on event selection algorithms and their performance.
