A minimal extension of the Standard Model with three heavy Majorana neutrinos simultaneously realizes fermionic dark matter, a strong first-order electroweak phase transition, and low-scale resonant leptogenesis consistent with neutrino data.
The Aligned 2HDM supports strong first-order electroweak phase transitions that yield LISA-detectable gravitational waves together with LHC-accessible signals from additional neutral and charged Higgs states.
A 2HDM extended by a complex singlet uses tree-level MPP to motivate degenerate neutral Higgs masses, yielding viable DM phenomenology and a thermally induced strong first-order electroweak phase transition.
