Towards the depth-dependent energy spectrum using stopping muons in IceCube — •Deborah Kramps and Lucas Witthaus for the IceCube collaboration — Astroparticle Physics WG Rhode, TU Dortmund University, Germany

The IceCube Neutrino Observatory is a cubic-kilometer-scale detection sys- tem located in the Antarctic ice, dedicated to the study of neutrinos. However, the predominant signal comes from atmospheric muons produced in extensive air showers in the atmosphere. These muons traverse the ice at speeds greater than the speed of light, producing Cherenkov light that is captured by optical modules. The muon energies can be reconstructed based on the recorded light patterns.

This talk presents a Monte-Carlo study aimed at unfolding the depth- dependent energy spectrum of atmospheric muons. It is based on a subset of single muons that stop within IceCube's instrumented volume. Deep neural networks are used to perform the event classification and reconstruction tasks.
