Title: Studying High pT muons in Cosmic-Ray Air Showers

Abstract

Most cosmic-ray air shower arrays have focused on detectingelectromagnetic shower particles and low energy muons. A few groups (mostnotably MACRO + EASTOP and SPASE + AMANDA) have studied the high energymuon component of showers. However, these experiments had small solidangles, and did not study muons far from the core. The IceTop + IceCubecombination, with its 1 km$$^2$$ muon detection area can study muons farfrom the shower core. IceCube can measure their energy loss ($dE/dx$),and hence their energy. With the energy, and the known distribution ofproduction heights, the transverse momentum ($$p_T$$) spectrum of high$$p_T$$ muons can be determined. The production of the semuons iscalculable in perturbative QCD, so the measured muon spectra can be usedto probe the composition of incident cosmic-rays.
