Unitarity constraints on scalar parameters of the Standard and Two Higgs Doublets Model
read the original abstract
Unitarity constraints on the scalar parameters both for the Standard Model and the general Two Higgs Doublet Model (THDM) are examined. In the case of the THDM with an exact discrete symmetry transformation, we show that the mass of the lightest CP-even Higgs boson ($M_h$) and $\tan\beta$ are strongly correlated and consequently a strong lower bound can be put on $M_h$ for large $\tan\beta$. It is also shown that the inclusion of the discrete symmetry breaking term relaxes the aforementioned correlation.

Strong First-Order Electroweak Phase Transitions and Gravitational Waves in the Normal Two-Higgs-Doublet Model: A Comparative Study of the Four Yukawa Types and Thermal Resummation Schemes
In the Normal 2HDM, SFOEWPTs are single-step and alignment-favoring across all four Yukawa types, yet Parwani versus Arnold–Espinosa resummation changes the viable heavy-mass range from ~1.6 TeV to ≲800 GeV and leaves...

Two-Component Dark Matter with an SU(2) Dark Sector
A hidden SU(2) gauge sector that breaks to a Z3-protected two-component dark matter scenario is shown to have parameter points satisfying existing constraints.
