Abstract

By treating CP-violating interaction of the electroweak bubble wall as a perturbative term, chiral charge flux through the bubble wall is estimated. It is found that the absolute value of the flux $F_{Q}$ has a sharp peak at $m_{0} \sim a \sim T$ with $F_{Q} / (u T^{3}) \sim 1 0^{- 3} (Q_{L} - Q_{R}) Δ θ$ . Here $m_{0}$ is the fermion mass, $1/ a$ is the wall thickness, $T$ is the temperature at which the bubbles are growing, $u$ is the wall velocity, $Q_{L (R)}$ is the chiral charge of the relevant left(right)-handed fermion and $Δ θ$ is the measure of CP violation.
