  Electroweak baryogenesis (EWBG) constitutes a theoretically compelling and
experimentally testable mechanism for explaining the origin of the baryon
asymmetry of the universe (BAU). New results for the electric dipole moment
(EDM) of the electron place significant constraints on the beyond Standard
Model CP-violation needed for successful EWBG. We show how new developments in
EWBG quantum transport theory that include CP-violating sources first order in
gradients imply more relaxed EDM constraints than implied by previous
approximation formulations. Consequently, EWBG remains viable even in light of
present EDM bounds. We also illustrate how these developments enable a more
realistic treatment of CP-conserving interactions that can also have a decisive
impact on the predicted BAU.
