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…
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…
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…
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…
The Right-Handed Slepton Bulk Regions for Dark Matter in the Generalized Minimal Supergravity (GmSUGRA)
Imtiaz Khan, Waqas Ahmed, Tianjun Li +1
We study the light right-handed slepton bulk regions for dark matter from the Generalized Minimal Supergravity (GmSUGRA) in the Minimal Supersymmetric Standard Model (MSSM). In our…
Revisit a realistic intersecting D6-brane with modified soft SUSY terms
Imtiaz Khan, Waqas Ahmed, Tianjun Li +1
Because there are a few typos in the supersymmetry breaking sfermion masses and trilinear soft term, regarding the current Large Hadron Collider (LHC) and dark matter searches, we…
Investigating the GmSUGRA in the MSSM through the long-lived bino NLSP at the HL-LHC
Wenxing Zhang, Waqas Ahmed, Imtiaz Khan +2
The axino, the supersymmetric partner of axion, is a well-motivated warm/hot dark matter candidate, and provides a natural solution to the relic density problem for the bino-like n…
Probing Relatively Heavier Right-Handed Selectron at the CEPC, and ILC
Waqas Ahmed, Imtiaz Khan, Tianjun Li +2
We employ the low energy Minimal Supersymmetric Standard Model (MSSM) to explore the parameter space associated with -pole and Higgs-pole solutions. Such parameter spaces can no…
