Reopen parameter regions in two-Higgs doublet models

The stability of the electroweak potential is a very important constraint for models of new physics.At the Washer Suspension Guide 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 AEG IAE84851FB 80cm Sensefry Maxisense Induction Hob be expected that radiative corrections to the potential are important.We study these effects at the example of the THDM type-II and find that loop corrections can revive more than 50% of the phenomenological viable points which are ruled out by the tree-level vacuum stability checks.Similar effects are expected for other extension of the standard model.
