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…
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…
Elastic toroidal vector dark matter through a dark photon in the LUX-ZEPLIN high recoil window
Imtiaz Khan, Salvatore Capozziello, G. Mustafa +4
The 2026 LUX-ZEPLIN search reports one nuclear recoil candidate at in an extended window reaching about . We con…
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…
Thermal Alignment as a Pathway to Axion Dark Matter
Imtiaz Khan, G. Mustafa, Chengxun Yuan +3
Thermal alignment cannot be inferred from the axion mean alone because the dissipative bath that erases the initial displacement also prepares field and momentum fluctuations. We d…
Conformal dark matter and MHz gravitational waves
Imtiaz Khan, Niamat Ullah, Salvatore Capozziello +2
A localized enhancement of the primordial curvature spectrum can leave two distinct relics: gravitationally produced conformal-fermion dark matter and a scalar-induced stochastic g…
Parametric Resonance of Higgsed Vector Dark Matter: Inflationary Initial Conditions and Sourced Displacements
Imtiaz Khan, Salvatore Capozziello, G. Mustafa +2
Parametric resonance in a Higgsed Abelian sector provides an efficient mechanism for producing vector dark matter, but its viability depends crucially on the origin of the initial…
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…
CMB Test of the Higgs Origin of Dark-Photon Dark Matter
Imtiaz Khan, Salvatore Capozziello, G. Mustafa +2
Laboratory searches determine the mass and kinetic mixing of dark-photon dark matter. The CMB isocurvature probes how its abundance depends on inflationary initial conditions. We f…
Long Inflation Screens Euclidean-Wormhole Initial States
Imtiaz Khan, Pirzada, G. Mustafa +2
Euclidean wormholes can prepare inflation in non--Bunch--Davies initial states, but long Lorentzian expansion screens this memory from the CMB. We derive a visibility bound for Euc…
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…
Dilaton-Induced Resonant Production of Ultralight Vector Dark Matter
Imtiaz Khan, G. Mustafa, Jehanzad Zafar +3
A dilatonic half-mass resonance can produce ultralight vector dark matter only if the Floquet instability becomes efficient before the oscillating spectator scalar dominates the co…
Post-Inflationary Quenched Production of Axion SU(2) Dark Matter
Imtiaz Khan, Pirzada, G. Mustafa
The relic abundance of vector dark matter originating from an inherited axion- condensate is typically determined by implementing an adiabatic matching procedure across the…
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…
