Cross sections and energy loss for lepton pair production in muon transport

摘要

We reevaluate electron-positron pair production from electromagneticinteractions of muons in transit through materials. Our approach, through theuse of structure functions for inelastic and elastic scattering and includinghadronic recoil, make the formalism useful for tau pair production at highenergies. Our results for electron-positron pair production agree well withprior evaluations. Tau pair production, has a significant contribution frominelastic scattering in addition to the usual coherent scattering with thenucleus and scattering with atomic electrons.
