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 ∼a ∼ T with F_Q/(uT^3) ∼10^-3(Q_L - Q_R)Δθ. 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 Δθ is the measure of CP violation.
