Theory SeminarEW baryogenesis in the aligned two Higgs doublet model
Shinya Kanemura (U Osaka)
We discuss baryon asymmetry of the Universe in the aligned two Higgs doublet model, in which coupling constants of the lightest Higgs boson with the mass 125 GeV coincide with those in the standard model at tree level to satisfy the current LHC data. In this model, the severe constraint from the data of the electric dipole moment (EDM) can be avoided by destructive interferences between CP-violating phases in Yukawa interactions and scalar couplings in the Higgs potential. We find that some benchmark points in the model can explain the observed baryon number density under current experimental data. We discuss how we can test this model using various future experiments such as collider, flavor, EDM as well as gravitational wave observations.
