Description

We discuss leptogenesis in the context of the recently proposed ``asymmetric texture'', where both quark and lepton masses and mixings are explained from $SU(5)$ grand unification and $\mathcal{T}_{13}$ family symmetry. In this setup, two large lepton mixing angles come from the tribimaximal (TBM) seesaw matrix with a phase and the small reactor angle is contributed entirely by the charged lepton sector. The phase in the TBM mixing leads to low energy Dirac and Majorana $CP$ violation. We show that these phases generate baryon asymmetry through leptogenesis only when flavor effects are considered. We investigate thermal leptogenesis in both non-resonant and resonant regimes and constrain the range of right-handed neutrinos for successful leptogenesis. We also show that the previously undetermined sign of the TBM phase can be determined from the sign of baryon asymmetry.
