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…

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.…
