Electroweak baryogenesis with lepton flavor violation

We investigate the feasibility of electroweak baryogenesis in a two-Higgs doublet model with lepton flavor violation. By scrutinizing the heavy Higgs boson mass spectrum, regions satisfying both strong first-order electroweak phase transition and the muon g - 2 anomaly are identified. We also estimate the baryon number density by exploiting extra Yukawa couplings in the mu-tau sector. It is found that a CP-violating source term can be enhanced by the mu-tau flavor-violating coupling together with the extra tau coupling. With O(1) Yukawa couplings and CP-violating phases, the observed baryon number density is marginally produced under a generous assumption for the bubble wall profile. (C) 2016 The Authors.
