Abstract
We consider the effects of particle transport in topological defect-me diated electroweak baryogenesis scenarios. We analyze the cases of bot h thin and thick defects and demonstrate an enhancement of the origina l mechanism in both cases due to an increased effective volume in whic h baryogenesis occurs. This phenomenon is a result of an imperfect can cellation between the baryons and antibaryons produced on opposite fac es of the defect.
