Abstract

We perform a fit of solar neutrino data in the framework of the two four-neutrino schemes that are compatible with the results of all neutrino oscillation experiments. These schemes allow simultaneous transitions of solar nu_e's into active nu_mu's, nu_tau's and sterile nu_s. The data imply that the SMA solution is valid for any combination of nu_e->active and nu_e->sterile transitions, whereas the LMA, LOW and VO solutions disappear when nu_e->nu_s transitions are dominant.
