Non-thermal Dark Matter in Extension of Inert Doublet Model
Maien Binjonaid, Ahmed Elsheshtawy, Shaaban Khalil
We propose an extension of the Inert Doublet Model (IDM) that explains both neutrino masses and dark matter (DM) in the intermediate-mass range by incorporating a gaug…

This paper investigates the possibility of Dark Matter (DM) fermions production alongside a gauge boson (A) using a model based on Einstein-Cartan gravity in an electron…
Higgs Quadruplet Impact on Mass Shift, Dark Matter, and LHC Signatures
Talal Ahmed Chowdhury, Kareem Ezzat, Shaaban Khalil +2
The addition of a Higgs quadruplet to the standard model (SM) of quarks and leptons would shift the boson mass upward. It could also facilitate the production of dark matter th…
