Abstract

We study the two-Higgs-doublet models with CP conservation. In particular, we consider the special form of the potential which has a single CP invariant stable minimum. We also comment on the bounds for the Higgs masses and couplings derived in these models.

    In contrast, the vacuum stability of non-supersymmetric models is still mainly checked at tree-level. For instance, the tree-level potential of two-Higgs doublet models (THDM) has been studied intensively in literature [26–34], and very compact conditions for the stability of the electroweak (ew) potential were found. These results where also generalised to other non-supersymmetric model [35–38].
