Tree-level unitarity constraints in the most general 2HDM
read the original abstract
We obtain tree-level unitarity constraints for the most general Two Higgs Doublet Model (2HDM) with explicit CP-violation. We briefly discuss correspondence between possible violation of tree level unitarity limitation and physical content of the theory.

Electro-Weak Phase Transitions and Collider Signals in the Aligned 2-Higgs Doublet Model
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.

Two Higgs doublet model with a complex singlet scalar and Multi-critical Point Principle
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.
