Analysis Of Neutrino Fluxes From Cosmic Rays Interactions In The Earth'S Atmosphere

The cosmic rays have a glorious century long history. They are an inexhaustible source of fundamental knowledge and practical applications. In this paper we have studied properties of neutrino fluxes which have originated from cosmic rays interactions in the Earth's atmosphere. Upward going neutrinos propagating through the Earth can undergo oscillation phenomena in matter. Therefore, knowledge of neutrino fluxes can help for the determination of the unknown yet neutrino parameters. Several useful analytical formulae have been obtained.
