Gravitational wave and electroweak baryogenesis with two Higgs doublet models

We study stochastic gravitational wave production and baryon number generation at electroweak phase transition with the two Higgs doublet models. The produced stochastic gravitational wave during the strongly first-order phase transition can be probed by future space-based interferometers. The nonlocal electroweak baryogenesis cannot address the observed Baryon asymmetry of the Universe successfully in the strongly first-order phase transition parameter spaces due to the CP violation phase is severely bounded by the electron electric dipole moment measurement ACMEII.

Automated summary

We investigate stochastic gravitational wave production and baryon number generation during the electroweak phase transition using the two Higgs doublet models. The stochastic gravitational waves produced during a strongly first-order phase transition can be detected by future space-based interferometers. However, the nonlocal electroweak baryogenesis fails to explain the observed Baryon asymmetry of the Universe in the parameter spaces of strongly first-order phase transition due to the severe constraint imposed by the measurement of the electron electric dipole moment by ACMEII.
