An improved muon track reconstruction for IceCube and IceCube-Gen2 — •Federica Bradascio — federica.bradascio@desy.de

IceCube is a cubic-kilometer Cherenkov telescope operating at the South Pole. Its goal is to detect astrophysical neutrinos and identify their sources. High-energy muon neutrinos are identified through the secondary muons produced via charge current interactions with the ice. The muon tracks are reconstructed using a maximum likelihood method which models the arrival times of Cherenkov photons registered by the photomultipliers. This work aims to improve the muon angular resolution of IceCube and its planned extension, IceCube-Gen2, to the sub-degree range. The current muon reconstruction assumes continuous energy loss along the muon track, and does not account for photomultiplier-related effects such as prepulses and afterpulses. In the reconstruction scheme presented here, the expected arrival time distribution has been modified to parameterize the stochastic muon energy losses.
