Abstract:
The neutrino oscillation experiments provide as with neutrino mass square differences, mixing angles and a possible hierarchy in the neutrino mass spectrum. The main physical goal in future experiment are the determination of the Maxing angle . In particular, the observation of is quite interesting for the point of view that related to the origin of the matter in the universe. One of the most important parameter in neutrino physics is the magnitude of Mixing angle and CP Phase . The oscillation data also suggest that the neutrinos may belong to either a normal hierarchy or an inverted hierarchy . The data do not exclude the possibility that the mass of the light neutrino could be much larger than , which would imply the possible existence of a quasi-degenerate neutrino mass spectrum . On the other hand, the actual mass of neutrinos cannot be extracted from these data, only the study of tritium single decay and nuclear neutrino-less double beta decay together can provide sharpest limit on the mass and nature of neutrinos.
