Description
Extensions of the two higgs doublet models with a singlet scalar can easily accommodate all current experi-
mental constraints and are highly motivated candidates for Beyond Standard Model Physics. It can success-
fully provide a dark matter candidate, explain baryogenesis and provide gravitational wave signals. In this
work, we focus on the dark matter phenomenology of the two higgs doublet model extended with a complex
scalar singlet which serves as the dark matter candidate. We study the variations of the dark matter observ-
ables, i.e relic density and direct detection cross-section, with respect to the model parameters. We obtain a
few benchmark points in the light and heavy dark matter mass region. We are also currently studying possi-
ble signatures of this model at current and future colliders and the possibility to distinguish this model from
other new physics scenarios.
