THE NEUTRINO MIXING MATRIX, NEUTRINO OSCILLATIONS, AND NEUTRINOLESS DOUBLE-BETA DECAY

The phenomenology of neutrino-mixing, neutrinoless double-beta decay and the connection to neutrino oscillations is reviewed. Recent values of the mixing angles from atmospheric and solar neutrino oscillation experiments are used to predict values of the effective Majorana mass of the electron neutrino. Prospective sensitivities of next generation experiments to constrain or measure the neutrino mass scale are discussed, as well as the possible impact of these experiments on neutrino dark matter.
