CP-VIOLATING BUBBLE WALL AND ELECTROWEAK BARYOGENESIS

Electroweak baryogenesis depends on the profile of the CP-violating bu bble wall created at the first order phase transition. We attempt to d etermine the profile by solving the coupled equations of motion for th e moduli and phases of the two Higgs doublets at the transition temper ature. A variety of CP-violating bubble walls are classified according to boundary conditions. We point out that a sufficiently small explic it CP violation gives nonperturbative effects to yield the baryon asym metry of the universe.
