Primordial black holes and scalar-induced gravitational waves in the supersymmetric 331 model from SU(6)
Imtiaz Khan, Niamat Ullah, Ali Muhammad +4
We study primordial black holes and scalar-induced gravitational waves in the supersymmetric 331 model based on SU(6). The inflaton continues to be the D-flat radial combination of…
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…
Thermal Higgsino Dark Matter in GmSUGRA for the LZ Event and Solar-Neutrino Constraint
Imtiaz Khan, Waqas Ahmed, Tianjun Li +2
We study the thermal Higgsino dark matter in the Minimal Supersymmetric Standard Model (MSSM) with Generalized Minimal Supergravity (GmSUGRA) boundary conditions after the high-rec…
REFLEX with Jev for Efficient Selective Control in LLM Agents
Tiantong Wu, Wei Yang Bryan Lim
LLM agents often use generative models for bounded decisions, raising the question of when these decisions can be handled more efficiently without reducing task success. We study R…
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…
Non-Minimal Dilaton Inflation from the Effective Gluodynamics
Pirzada, Imtiaz Khan, Mussawair Khan +2
We develop a nonminimal dilaton-inflation model in which the inflaton is the lightest scalar excitation of a hidden confining gauge theory. The Migdal--Shifman anomaly-matching act…
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…
Revisiting the Electroweak Supersymmetry from the Generalized Minimal Supergravity
Imtiaz Khan, Ali Muhammad, Tianjun Li +1
We explore the Electroweak Supersymmetry (EWSUSY) scenario within the Minimal Supersymmetric Standard Model (MSSM) under the Generalized Minimal Supergravity (GmSUGRA) framework, g…
Revisiting the Realistic Intersecting D6-Brane Model with positive and negative μ Terms
Imtiaz Khan, Ali Muhammad, Tianjun Li +1
In light of current constraints from supersymmetry (SUSY) searches within the LHC, as well as findings from direct dark matter detection experiments such as LUX-ZEPLIN (LZ), we rev…
The Light Neutralino Dark Matter in the Generalized Minimal Supergravity (GmSUGRA)
Imtiaz Khan, Waqas Ahmed, Tianjun Li +2
We investigate both the and poles solutions for the Higgsino mass parameter and for the neutralino dark matter in light of the LHC supersymmetry searches and th…
