CHIRAL CHARGE FLUX AND ELECTROWEAK BARYOGENESIS

By treating CP-violating interaction of the electroweak bubble wall as a perturbative term, chiral charge flux through the bubble wall is es timated. It is found that the absolute value of the flux F-Q has a sha rp peak at m(0) similar to a similar to T with F-Q/(uT(3)) similar to 10(-3) (Q(L) - Q(R)) Delta theta. Here m(0) is the fermion mass, 1/a i s the wall thickness, T is the temperature at which the bubbles are gr owing, u is the wall velocity, Q(L(R)) is the chiral charge of the rel evant left (right)-handed fermion and Delta theta is the measure of CP violation.
