Quantum transport and electroweak baryogenesis

We review the mechanism of electroweak baryogenesis. Our focus is on the derivation of quantum transport equations from first principles within the Schwinger–Keldysh formalism. We emphasize the importance of the semiclassical force approach, which provides reliable predictions in most models. In light of recent electric dipole moment measurements and given the results on new physics searches from collider experiments, the status of electroweak baryogenesis is discussed in a variety of models.
