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.
