Unfolding of the energy spectrum of stopping muons in IceCube — •Hubertus Kaiser and Jan Soedingrekso for the IceCube collaboration — TU Dortmund, Dortmund, Germany

The investigation of neutrinos and their origin is one of the main objectives of IceCube Neutrino Observatory. A classification of measured events into atmospheric muons and neutrinos is essential, as most events are of atmospheric nature and form the background in the search for extragalactic neutrino sources. Therefore an accurate selection of atmospheric muons and a precise determination of their energy spectrum provide the basis for further analysis. This talk gives insights into the selection of single stopping muons using machine learning algorithms and how their energy spectrum can be unfolded.
