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…
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…
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…
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…
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.…
