摘要

High-energy neutrinos, arising from decays of mesons produced through the collisions of cosmic ray particleswith air nuclei, form the background in the astrophysical neutrino detection problem. An ambiguity in high-energybehavior of pion and especially kaon production cross sections for nucleon-nucleus collisions may affect essentially thecalculated neutrino flux. We present results of the calculation of the energy spectrum and zenith-angle distribution ofthe muon and electron atmospheric neutrinos in the energy range 10 GeV to 10 PeV. The calculation was performedwith usage of known hadronic models (QGSJET-II, SIBYLL 2.1, Kimel & Mokhov) for two of the primary spectrumparametrizations, by Gaisser & Honda, and by Zatsepin & Sokolskaya. The comparison of zenith angle-averaged muonneutrino spectrum with the measurement data in IceCube experiment make it clear that even at energies above 100 TeVthe prompt neutrino contribution is not so apparent because of tangled uncertainties of the strange (kaons) and charm(D-mesons) particle production cross sections. An analytic description of calculated neutrino fluxes is presented.
