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.

Fate of Metastable Vacua in the Type-II Two-Higgs Doublet Model
In the Type-II two-Higgs-doublet model, once next-to-leading-order unitarity, perturbativity and current data are imposed, the electroweak vacuum remains the global minimum among neutral vacua at tree level and one lo...

GOOFy fermions
New fermion transformations and all-order renormalization-invariant parameter regions are identified for two-Higgs-doublet models including scalar-fermion interactions.

On vacua and bounded masses in the general 2HDM
In general 2HDM potentials with two local minima, all scalar masses remain bounded under perturbativity constraints on the quartic couplings.

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.

Light states in real 3HDMs with spontaneous CP violation and softly broken symmetries
In real 3HDMs with spontaneous CP violation and discrete symmetry on quartics, perturbativity bounds keep new scalars near the electroweak scale despite large quadratic terms.
