Multi Component Dark Matter in a Minimal Model
Karim Ghorbani
We study a minimal -symmetric extension of the Standard Model containing two singlet fermions and a singlet scalar that interact with the SM particles through the Hig…
Fermion Dark Matter Effect on Electroweak Phase Transition
Soudeh Mirzaie, Karim Ghorbani, Parsa Ghorbani
The addition of extra scalars to the Standard Model (SM) of particle physics enriches the vacuum structure and consequently gives rise to strong first-order phase transitions (EWPT…
Loop quantum effects on direct detection prediction in two-scalar dark matter scenario
Karim Ghorbani, Parsa Ghorbani
We investigate the effect of quantum corrections on the elastic scattering cross section of dark matter off nucleus in two-scalar dark matter model. Among two extra singlet scalars…
Secluded Scalar Dark Matter and the Muon Anomalous Magnetic Moment
Karim Ghorbani
We consider a dark matter model with a singlet scalar, , as our dark matter (DM) candidate which is secluded from the Standard Model (SM) and annihilates to the singlet scalar,…
