NEUTRINO OSCILLATIONS, MASSES AND MIXING

W. M. Alberico, S. M. Bilenky

The original B. Pontecorvo idea of neutrino oscillations is discussed. Neutrino mixing and basics of neutrino oscillations in vacuum and in matter are considered.
Recent evidences in favour of neutrino oscillations, obtained in the Super-Kamiokande, SNO, KamLAND and other neutrino experiments are discussed. Neutrino oscillations in the solar and atmospheric ranges of the neutrino mass-squared differences are considered in the framework of the minimal scheme with the mixing of three massive neutrinos.
Results of the tritium b-decay experiments and experiments on the search for neutrinoless double b decay are briefly discussed.
