A Second Higgs Doublet in the Early Universe: Baryogenesis and
  Gravitational Waves
  We show that simple Two Higgs Doublet models still provide a viable
explanation for the matter-antimatter asymmetry of the Universe via electroweak
baryogenesis, even after taking into account the recent order-of-magnitude
improvement on the electron-EDM experimental bound by the ACME Collaboration.
Moreover we show that, in the region of parameter space where baryogenesis is
possible, the gravitational wave spectrum generated at the end of the
electroweak phase transition is within the sensitivity reach of the future
space-based interferometer LISA.
