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