Abstract

We study the CP-violating bubble wall by solving the coupled equations of motion derived from the two-Higgs-doublet model for the moduli ρ_i and phases θ_ i of the two scalars (i=1,2) at the transition temperature. We find a solution that the CP-violating phase θ≡θ₁-θ₂ connecting the CP-conserving vacua strongly violates CP in the intermediate region while the moduli largely deviate from the kink shape there. We estimate the chiral charge flux through the wall surface, which may be efficient enough to produce the baryon asymmetry by the sphaleron process.
