Reopen parameter regions in Two-Higgs Doublet Models

Understand

The stability of the electroweak potential is a very important constraint for models of new physics.

• At the moment, it is standard for Two-Higgs doublet models (THDM), singlet or triplet extensions of the standard model to perform these checks at tree-level.
• However, these models are often studied in the presence of very large couplings.
• Therefore, it can be expected that radiative corrections to the potential are important.
