Query: Atmospheric neutrinos from charm   Using next-to-leading order perturbative QCD, we find that the charm
contribution to the atmospheric lepton fluxes dominates over the conventional
ones from pi and K decays for energies higher than 10^5 GeV. We also discuss
theoretical uncertainties involved in the calculations and compare our results
with previous evaluations.
