Description
We extend the two-Higgs doublet models of Type I and Type II by adding a real gauge-singlet scalar S which is the Dark Matter (DM) candidate (2HDMS models). We impose theoretical constraints derived from perturbativity, stability, unitarity and correct electroweak symmetry breaking and require that one of CP-even Higgs bosons fit the LHC data for the ∼125.5 GeV state at the 68%~C.L. after including existing constraints from LEP and B physics and LHC limits on the heavier Higgs bosons. We investigate properties of the model and discuss possibilities to fit experimental data on dark matter.
