摘要：

We consider the effects of particle transport in topological defect-mediated electroweak baryogenesis scenarios. We analyze the cases of both thin and thick defects and demonstrate an enhancement of the original mechanism in both cases due to an increased effective volume in which baryogenesis occurs. This phenomenon is a result of an imperfect cancellation between the baryons and antibaryons produced on opposite faces of the defect.
