Abstract

With the Large Hadron Collider (LHC) running, we should probe electroweak baryogenesis (EWBG) while probing CP violation (CPV) with electron electric dipole moment (eEDM). Rooted in the flavor structure of the Standard Model (SM), the general two Higgs doublet model (g2HDM) with a second set of Yukawa couplings can deliver EWBG while surviving eEDM. We point out a chiral-enhanced top-bottom interference effect that makes b→sγ decay an exquisite window on EWBG and eEDM, and illustrate the importance of the ΔACP observable at Belle II.
