摘要：We consider the non-standard matter effect in flavor conversion of neutrinos crossing the core of the Earth. We show that oscillations of core-crossing neutrinos with E 0.5 GeV can well be described by first order perturbation theory. We show that due to the non-standard matter effect a varying chemical composition in the Earth can modify the neutrino flavor conversion by 100%. The effects of CP violating phases in non-standard neutral current interactions are emphasized in particular.
