New results on muon inelastic cross section and energy loss in rock

TL;DR

This paper examines uncertainties in muon inelastic cross section and energy loss calculations, highlighting how common approximations cause deviations, especially affecting heavier leptons like tau, with implications for related physics studies.

Contribution

It provides new correction estimates for muon inelastic cross section and energy loss calculations, emphasizing the impact of approximations and lepton mass effects.

Findings

Corrections increase with lepton mass.

Common kinematic approximations cause deviations.

Implications for tau-lepton energy loss are discussed.

Abstract

Various uncertainties in calculations of inelastic cross section and energy loss are considered. It is shown that widely used kinematic neglects and approximations result in deviations in calculations of these values. The obtained corrections increase with lepton mass, therefore possible consequences for tau-lepton are discussed, too.
