Abstract

Mass generation is one challenging open problems in particle physics. In this project, we will try to understand the pattern and hierarchy of neutrino masses. Why is so different from other fermions of the Standard Model? This pattern was build up from the observation of neutrino oscillation, from evidence of many different experiments. This is called the indirect evidence for neutrino masses. For other side, we don't have direct evidence of neutrino masses. We will review the phenomenology of direct evidences of neutrino masses and the role of new experiments to elucidate the pattern of the neutrinos masses. Finally, neutrinos are neutral particles and from that neutrinos can have diverse properties that charged leptons cannot have. One example, is the type of masses,neutrinos can have masses of Dirac type or masses of the Majorana type. This possibility is testable in neutrino less double beta decay experiments. (AU)
