Lepton energy loss spectra in inelastic scattering off nuclei

A hybrid model of lepton-nuclear interactions is constructed; energy loss spectra and average muon and tau lepton energy losses in inelastic scattering off nuclei in matter and water in the energy range 10 2 - 10 9 GeV are calculated in the framework of this model. Charge asymmetry of scattering due to processes with weak neutral current is discussed. Comparison with calculations in the framework of other models is presented. PACS numbers:
