Echoes of the Electroweak Phase Transition: Discovering a Second Higgs Doublet through A0 arrow right ZH0

The existence of a second Higgs doublet in nature could lead to a cosmological first-order electroweak phase transition and explain the origin of the matter-antimatter asymmetry in the Universe. We obtain the spectrum and properties of the new scalars H0, A0, and H+ or - that signal such a phase tra...
