Descripción
In this work we show a complete development for three neutrino oscillation taking into account the matter effect from the open quantum system approach. Open quantum system approach has a rigorous set of the statements and when it is applied on neutrino oscillation, due to dissipative phenomena, the neutrinos exhibit new and peculiar effects, in special, decoherence and relaxation. We use the most effective dissipators and we study which the possible neutrino behavior considering the LBNE experiment. LBNE is an experiment that belongs to next generation of the experiments and it will go to test the actual paradigm of neutrino oscillation. So, the study about which kind of the unusual effects that can happen it is important. In particular, we show how each kind of dissipative effect is linked to each mixing angle and consequently, we can leave evident the new effect in the survival and appearance probabilities. Interesting enough, in the LBNE case we present a new behavior at matter resonance region that can be seen even when the dissipative effect is small compared with energy dependent oscillation parameters.
