Abstract

The aim of this project has three parts: The first one is to write articles with the the main results of the phenomenological and systematic study about the dissipative process in neutrino oscillation in vacuum and matter between two families. These results were recently obtained in Ph. D. program of candidate. The second one is related with the systematic study of dissipative effects in three families neutrino oscillation in vacuum, where we will investigate: decoherence, relaxation and decay, where all this effects occurring duo to coupling between the neutrinos and a reservoir at constant temperature. Finally, to analyze the results and to put limits in the dissipative parameter and CP phase, we will apply this phenomenology in some experiments. (AU)
