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…
Predictions for in BLSSM with Inverse seesaw
Dris Boubaa, Shaaban Khalil
The persistent deviations observed in semileptonic decays, in particular the lepton flavor universality ratios and , provide intriguing…
Probing Right Handed Neutrino assisted Reheating with Gravitational Waves and Leptogenesis
Arghyajit Datta, Shaaban Khalil, Rajat Kumar Mandal +1
We investigate a non-instantaneous reheating period in the early Universe, where the inflaton field decays exclusively to right-handed neutrinos (RHNs). The subsequent decay of the…
t-channel dark matter at the LHC -- a whitepaper
Chiara Arina, Benjamin Fuks, Luca Panizzi +67
This report, summarising work achieved in the context of the LHC Dark Matter Working Group, investigates the phenomenology of -channel dark matter models, spanning minimal setup…
Unveiling ESSM Scalar Diquarks at the HL-LHC
Murad Ali, Shaaban Khalil, Stefano Moretti +2
We investigate the phenomenology of scalar diquarks with sub-TeV masses within the framework of the Supersymmetric Standard Model (ESSM) at the Large Hadron Collider (LHC…
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…
Flavor Violations in -Mesons within Non-Minimal SU(5)
Bhubanjyoti Bhattacharya, Alakabha Datta, Gaber Faisel +2
Recent anomalies in -meson decays, such as deviations in and , suggest possible lepton flavor universality violation and new exotic interactions. I…
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…
Higgs Vacuum Stability in extended Standard Model
Alakabha Datta, A. Elsayed, S. Khalil +1
We study vacuum stability of B-L extension of the Standard Model (SM) and its supersymmetric version. We show that the generation of non-vanishing neutrino masses through TeV inver…
