Neutrino oscillation effect on the indirect signal of neutralino dark matter from the Earth core

Abstract

We investigate the effect induced by neutrino oscillation on the dark matter indirect detection signal which consists in a muon neutrino flux produced by neutralino annihilation in the Earth core. We consider the neutrino oscillation parameters relevant to the atmosferic neutrino deficit, both in the nu_mu -> nu_tau and nu_mu -> nu_s cases.
