New LHC benchmarks for the $$\mathcal{CP}$$conserving twoHiggsdoublet model
We introduce a strategy to study the parameter space of the general, CPconserving, twoHiggsdoublet Model (2HDM) with a softly broken $$\mathbb Z_{2}$$symmetry by means of a new “hybrid” basis. In this basis the input parameters are the measured values of the mass of the observed Standard Model (SM)like Higgs boson and its coupling strength to vector boson pairs, the mass of the second CPeven Higgs boson, the ratio of neutral Higgs vacuum expectation values, and three additional dimensionless parameters. Here, using the hybrid basis, we present numerical scans of the 2HDM parameter space where we survey available parameter regions and analyze model constraints. From these results, we define a number of benchmark scenarios that capture different aspects of nonstandard Higgs phenomenology that are of interest for future LHC Higgs searches.
