Effect of neutral current interactions on high energy muon and electron neutrino propagation through the Earth

Abstract
High energy electron and muon neutrino propagation through the Earth has been performed using the Monte Carlo technique. We focused our attention on the effect of neutral current deep inelastic interactions compared to that of charged current ones. We have found that NCs do not produce any significant effect with respect to the case in which only CCs are considered. Therefore we conclude that NC interactions can be neglected without considerable loss of accuracy. When computing upward-going neutrino fluxes a simple formula describing the transmission probability, that depends on the neutrino direction and energy and the CC cross section, can be used to account for the Earth shadowing effect.
