Neutrino masses and mixing
Copyright policy )Neutrino masses and mixing
Restrictions on the neutrino masses and lepton mixing are reviewed. Solar, atmospheric and relic neutrinos give the indications of existence of nonzero neutrino masses and mixing. The data pick up two regions of mixing angles which are or appreciably larger or appreciably smaller than the Cabibbo angle. Some theoretical schemes with {\it large} or {\it small} lepton mixing are discussed.
