Pseudo-Nambu-Goldstone Boson Motion from Thermal Thresholds
Mussawir Khan, Ali Muhammad, Tianjun Li
Coherent motion of light scalar fields in the early Universe is typically attributed to an initial displacement, a primordial velocity, or a prescribed temperature-dependent potent…
LZ-Motivated Pseudo-Dirac Higgsinos in the Supersymmetric 331 Model from the Supersymmetric \texorpdfstring{}{SU(6)} GUT Model
Imtiaz Khan, Ali Muhammad, G. Mustafa +3
The high-recoil event reported by LUX--ZEPLIN motivates a neutral electroweak state with an inelastic splitting in the sub-MeV range. We propose supersymmetric 331 model from the s…
Light Neutralino Dark Matter in a Supersymmetric Pati-Salam Framework
Ali Muhammad, Imtiaz Khan, Tianjun Li +2
We investigate the low-energy phenomenology of the MSSM arising from the supersymmetric Pati-Salam framework, focusing on neutralino dark ma…
Dilaton-Flattened Axion Inflation
Pirzada, Ali Muhammad, Tianjun Li +2
We present a solvable same-sector effective theory for anomaly-inspired axion inflation, in which a heavy trace-anomaly mode dynamically backreacts on the axion potential. The tree…
LHC Run-3, Dark Matter and Supersymmetric Spectra in the Supersymmetric Pati-Salam Model
Ali Muhammad, Imtiaz Khan, Tianjun Li +3
Driven by the growing agreement between the experimentally measured muon anomalous magnetic moment and its SM prediction, we reexamine phenomenological consequences of the MSSM, wh…
The Light Neutralino Dark Matter at Future Colliders in the MSSM with the Generalized Minimal Supergravity (GmSUGRA)
Imtiaz Khan, Ali Muhammad, Tianjun Li +3
We perform a detailed investigation of light right-handed slepton bulk regions, together with the Higgs- and -resonance regimes, in the Minimal Supersymmetric Standard Model (MS…
