摘要：

In this work we present an analytic calculation of the mu(+/-) and neutrino fluxes in the earth's atmosphere. We discuss in detail the ratios nu(mu)/(nu) over bar (mu), nu(e)/(nu) over bar (e) and mu(+)/mu(-) as a function of particle energy and zenith angle. Precise knowledge of the neutrino/antineutrino ratios is necessary for the correct interpretation of neutrino oscillation experiments that use atmospheric neutrinos because of the different oscillation properties of neutrinos and antineutrinos in matter due to the Mikheyev-Smirnov-Wolfenstein mechanism. We also discuss the relation between muon and neutrino fluxes and the possibility to determine experimentally the non-oscillation neutrino fluxes from precise measurements of the muon flux.
