I reevaluate the total cross section and energy loss parameter [beta] for lepton pair production from interactions of high energy muons with atomic targets. Using a detailed structure function analysis, this evaluation is valid for both elastic and inelastic scattering and includes the entire range of allowed momentum transfers. The formalism presented here is applied to both e+e- and T+T- pair production. This approach to the calculation of the cross section allows for a numerical evaluation of the energy distribution of the differential cross section. Using this numerical evaluation, and parameterizations for the atmospheric muon flux, I calculate the differential flux of high energy electrons and taus produced underground from incident muons, considering both conventional and prompt atmospheric muon fluxes. An approximate form for the differential charged current neutrino cross section is presented and used to calculate the differential flux of electrons and taus produced from incident neutrinos to compare to the production by incident muons. I also calculate the underground flux of photons produced via muon bremsstrahlung and discuss the electromagnetic background from these events. The relevance of high energy lepton production for underground Cherenkov detectors is discussed.

The hadroproduction of lepton pairs with mass Q and finite transverse momentum Q{sub T} is described in perturbative QCD by the same partonic subprocesses as prompt photon production. The authors demonstrate that, like prompt photon production, lepton pair production is dominated by quark-gluon scattering in the region Q{sub T}> Q/2. This feature leads to sensitivity to the gluon density in kinematical regimes accessible in collider and fixed target experiments, and it provides a new independent method for constraining the gluon density.

They demonstrate that, like prompt photon production, lepton pair production is dominated by quark-gluon scattering in the region Q{sub T}> Q/2. This leads to sensitivity to the gluon density in kinematical regimes that are accessible both at collider and fixed target experiments while eliminating the theoretical and experimental uncertainties present in prompt photon production.
