Abstract Observed Matter - antimatter asymmetry and smallness of neutrino masses evidenced by experimental data are two fundamental problems of particle physics, which can be related if neutrinos are Majorana particles. The scenario in which this can occur is called LeptogenesisIn some theoretical beyond Standard Model contexts it is possible achieve bariogenesis through leptogenesis with the additional advantage of relating Universe barionic assymetry not only with low energy neutrino physics but with LHC physics. However, standard description suffers conceptual problems coming from the fact that Leptogenesis is described using the Boltzmann equation, which is a semiclassical equation that do not include quantum effects. The first principles formalism that includes those effects, called Schwinger-Keldysh formalism, must by applied in order to obtain a proper and complete description of the same. This Doctoral project aims to explore the fenomenology of some of this scenarios from the point of view of Schwinger-Keldysh formalism, and it is a natural continuation of student master's project.
