Scalar triplet leptogenesis in the presence of right-handed neutrinos with S₃ symmetry

Leptogenesis appears to be a viable alternative to account for the baryon asymmetry of the Universe through baryogenesis. In this context, we consider a scenario in which the standard model is extended with S ₃ and Z ₂ symmetry in addition to the two scalar triplets, two scalar doublets and three right-handed neutrinos. Presence of scalar triplets and right-handed neutrinos in the scenarios of both type-I and type-II seesaw frameworks provide a different leptogenesis option and can help us to understand the matter-antimatter asymmetry with simple S ₃ symmetry. We discuss the neutrino phenomenology and leptogenesis in both high (O(10¹⁰) GeV) and low energy scale (O(2) TeV) by constraining the Yukawa couplings. Moreover, we also consider the constraints on model parameters from neutrino oscillation data and leptogenesis to explain the rare lepton flavor violating decay and muon g-2 anomaly. (paper)
