Description
Cosmic rays incident on the Earth produce neutrinos through the interaction with nuclei in the atmosphere. At the energies above about 1 PeV, neutrinos from the charmed hadron decay (prompt neutrinos) dominate those from the pion and kaon decay (conventional neutrinos). The prompt neutrinos are important because they are the background to the astrophysical neutrinos.
We calculate the fluxes of the prompt atmospheric muon neutrinos in the different frameworks: perturbative QCD and the dipole model, using the most recent versions of the PDFs and the cosmic ray spectrum. Nuclear effects are included and their impact is investigated. We compare the results from the various models and estimate the uncertainties. The new calculation of the prompt atmospheric tau neutrino flux is also presented.
