Penumbral Inflation from Calabi-Yau Boundaries
Pirzada, Tianjun Li
Mapping Calabi-Yau geometry to early Universe cosmology remains a primary goal in string phenomenology. We present an inflationary mechanism where flux stationarity shifts the fiel…
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…
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…
