Neutrino Oscillations with Four Generations

Abstract

Recent status of neutrino oscillation phenomenology with four neutrinos is reviewed. It is emphasized that the so-called (2+2)-scheme as well as the (3+1)-scheme are still consistent with the recent solar and atmospheric neutrino data.Comment: 13 pages, 4 sets of figures, uses sprocl, epsfig.
