Description
We present IceCube measurements of the atmospheric muon energy spectrum from the sub-TeV to the PeV scale, obtained by unfolding energy-sensitive observables for two complementary event classes. Stopping muons contained within the in-ice detector provide sensitivity in the few-hundred-GeV to 10 TeV range, while through-going muons extend the measurement to higher energies where the prompt contribution and cosmic-ray model dependence become relevant.
Machine-learning-based reconstructions and event selections are developed to improve energy resolution and background rejection, enabling a stable unfolding. We present the resulting unfolded spectra and discuss their implications for hadronic production models and the composition of the atmospheric lepton flux.
