Four-neutrino mixing and long-baseline neutrino oscillation experiments

Abstract

We consider the two schemes with four massive neutrinos which are compatible with the results of all neutrino oscillation experiments. We show that in these two schemes the probabilities of nu_e disappearance and nu_mu->nu_e appearance in long-baseline experiments are strongly suppressed.
