We show that the existing neutrino oscillation data are in favour of the schemes with mixing of four massive neutrinos and that only two of these schemes, with two pairs of neutrinos with close masses separated by a gap of about 1 eV, are…
We discuss all possible schemes with four massive neutrinos inspired by the existing experimental indications in favour of neutrino mixing, namely the atmospheric, solar and LSND neutrino experiments. We argue that the scheme with a…

We show explicitly that four neutrino models of the 2+2 variety still provide an acceptable global fit to the solar, atmospheric and LSND neutrino data. The goodness of fit, defined in the usual way, is found to be 0.26 for the simplest…
We present a four-neutrino model with three active neutrinos and one sterile neutrino which naturally has maximal $\nu_\mu\to\nu_\tau$ oscillations of atmospheric neutrinos and can explain the solar neutrino and LSND results. The model…
Models with three active neutrinos and one sterile neutrino can naturally account for maximal oscillations of atmospheric neutrinos, explain the solar neutrino deficit, and accommodate the results of the LSND experiment. The models predict…
