The three- and four-Higgs couplings in the general two-Higgs-doublet model
The three- and four-Higgs couplings in the general two-Higgs-doublet model
We apply the unitarity bounds and the bounded-from-below (BFB) bounds to the most general scalar potential of the two-Higgs-doublet model (2HDM). We do this in the Higgs basis, i.e. in the basis for the scalar doublets where only one doublet has vacuum expectation value. In this way we obtain bounds …
