| Abstract | We explore lepton-flavored electroweak baryogenesis, driven by CP-violation in leptonic Yukawa sector, using the tau - mu system in the two Higgs doublet model as an example. This setup generically yields, together with the flavor-changing decay h -> tau mu, a tree-level Jarlskog invariant that can drive dynamical generation of baryon asymmetry during a first-order electroweak phase transition and results in CP-violating effects in the decay h -> tau tau. We find that the observed baryon asymmetry can be generated in parameter space compatible with current experimental results for the decays h -> tau mu, h -> tau tau, and tau -> mu gamma, as well as the present bound on the electric dipole moment of the electron. The baryon asymmetry generated is intrinsically correlated with the CP-violating decay h -> tau tau and the flavor-changing decay h -> tau mu, which thus may serve as "smoking guns" to test lepton-flavored electroweak baryogenesis. |
