Description
We present a simple extension of the Standard Model with three right-handed neutrinos with an additional U(1$)_\text{F}$ abelian flavor symmetry, with a non standard leptonic charge $L_e-L_\mu-L_\tau$ for lepton doublets and arbitrary right-handed charges. We present a see-saw realization of such a scenario. The baryon asymmetry of the Universe is generated via thermal leptogenesis through CP-violating decays of the heavy sterile neutrinos. We present a detailed numerical solution of the relevant Boltzmann equations in two different scenarios: three quasi-degenerate heavy Majorana neutrino masses and a hierarchical mass spectrum.
