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

Chiaki Nose, Chikako Idegawa, Gi-Chol Cho

Imposing the tree-level multiple point principle in a two-Higgs-doublet model with a complex singlet scalar still permits viable dark matter parameter regions and a thermally driven strong first-order electroweak phase transition.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Viable parameter regions still exist in which the observed DM constraints are satisfied, and thermal loop effects can induce a strong first-order electroweak phase transition compatible with electroweak baryogenesis.

C2weakest assumption

The tree-level multiple point principle is imposed by hand to enforce vacuum degeneracy, and the resulting large doublet-singlet mixing is assumed to be compatible with the degenerate scalar scenario after all constraints are applied.

C3one line summary

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.
