Abstract
We study electroweak baryogenesis driven by the top quark in a general two Higgs doublet model with flavor-changing Yukawa couplings, keeping the Higgs potential CP invariant. With Higgs sector couplings and the additional top Yukawa coupling rho(tt) all of O(1), one naturally has sizable CP violation that fuels the cosmic baryon asymmetry. Even if rho(tt) vanishes, the favor-changing coupling rho(tc) can still lead to successful baryogenesis. Phenomenological consequences such as t -> ch, tau -> mu gamma electron electric dipole moment, h -> gamma gamma, and hhhcoupling are discussed. Published by Elsevier B.V
