Z'-Mediated Slepton and Sneutrino Signatures at HL-LHC
Kareem Ezzat, Nidal Chamoun, Shaaban Khalil
We investigate the discovery potential of a heavy boson as a portal to charged sleptons and right-handed sneutrinos within the Supersymmetric Standard Model (BLSSM) at t…

Exploring and Right-Handed Neutrinos in the BLSM at the Large Hadron Collider
Nidal Chamoun, Kareem Ezzat, Shaaban Khalil +1
We study the collider phenomenology of the - extension of the Standard Model (BLSM), focusing on the production and decay of a heavy neutral gauge boson (\( Z' \)) at the Lar…

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…
