Description
We investigate dark matter and gravitational wave production in a type II 2HDM with the addition of an inert complex singlet. A symmetry is imposed under which the doublets are even and the singlet is odd to ensure the stability of the dark matter candidate. When the singlet obtains a VEV, only the pseudoscalar component of the singlet contributes to the dark matter sector. When the singlet does not obtain a VEV, both the neutral scalar and pseudoscalar components of the singlet contribute to the dark matter sector. We compare dark matter production between a zero and a nonzero singlet VEV after the EWPT. Future experiments could also observe gravitational waves produced by this phase transition.
