Abstract

In this paper, we analyse resonant leptogenesis in a low scale inverse seesaw model with A₄ flavor symmetry, in a model we explored earlier to explain light neutrino masses and mixings, and also charged lepton flavor violating decay μ→ eγ. Six A₄ scalar singlets and one A₄ fermion triplet are included, which are charged under the group A₄× U(1)_X × Z₅ × Z₄ , with at least two degenerate RH (Right Handed) neutrinos. The light neutrino masses and leptogenesis both share a same origin with the heavy right handed neutrinos. Thus, we expound the possibility of generating resonant leptogenesis in this model at energies as low as 1 TeV. We then analyse our findings to envision if our model inclines more towards weak or strong washout.
