The atmospheric lepton fluxes from the decays of charmed hadrons generated by the interactions of primary cosmic rays with air nuclei in the upper atmosphere are evaluated at next-to-leading order in perturbative quantum chromodynamics and the results are compared with previous calculations. The theoretical uncertainties involved in the evaluation are also discussed. We find that the charm contribution to the atmospheric muon flux dominates over the conventional one from pion and kaon decays for energies higher than 105 GeV. The ntN-->tX event rate per year for a detector with a water equivalent volume of 1 km3 is evaluated both in absence of oscillations and assuming nm-->nt oscillations according to the results of Super- Kamiokande. The atmospheric tau neutrino flux is found to dominate over the tau neutrino flux produced by oscillations of atmospheric muon neutrinos for energies above a few hundred GeV. The fluxes of muons and muon neutrinos from the decays of pions and kaons that are themselves the decay products of charmed hadrons produced by the interactions of cosmic rays with the atmosphere are also evaluated using next- to-leading order perturbative quantum chromodynamics, and we find that they are two to three orders of magnitude smaller than the fluxes from the decays of pions and kaons directly produced by the interactions of cosmic rays with the atmosphere.
