High-Energy Atmospheric Muons in IceCube and IceTop — •Frederik Tenholt for the IceCube collaboration — Ruhr-Universität Bochum

High-energy atmospheric muons can yield information about the prompt contribution to atmospheric lepton fluxes also relevant for neutrino studies as well as complement results from collider experiments in the forward region of particle physics.

In this talk, two different analyses studying high-energy atmospheric muons are presented. In order to obtain a suitable event sample, cut parameters capable of tagging events that contain a muon dominant within the bundle are introduced and validated. In the first analysis, the resulting sample is used to obtain the differential muon flux between ∼ 6 TeV and ∼ 400 TeV in the zenith range 0^∘ < θ < 34.6^∘. In the second analysis, a proof of concept for the measurement of an effective Feynman-x of atmospheric muons, quantifying the forwardness of these particles, is presented, resulting in an observable well correlated with the true value obtained from simulations.
