We study the complementarity between the Large Hadron Collider (LHC) and future lepton colliders in probing electroweak baryogenesis induced by an additional bottom Yukawa coupling ρbb. The context is general two Higgs doublet model (g2HDM) where such additional bottom Yukawa coupling can account for the observed baryon asymmetry of the Universe if Im(ρbb) & 0.058. We find that LHC would probe the nominal Im(ρbb) required for baryogenesis to some extent via bg → bA → bZh process if 300 GeV . mA… Expand

Electroweak baryogenesis from light fermion sources: a critical study
Electroweak baryogenesis (EWBG) is sourced by nonstandard CP -violating interactions of the Higgs boson with fermions, usually taken to be the top quark, enhanced by its large Yukawa coupling.Expand
