F-Term Hybrid Inflation with T-Model Kähler Geometry and Beyond

Waqas Ahmed, Constantinos Pallis, Mansoor Ur Rehman

We analyze F-term hybrid inflation (FHI) within various grand unified theories (GUTs) in the presence of a Kähler potential for the inflaton field which parameterizes the Kähler ma…

GUT-Scale Smooth Hybrid Inflation with a Stabilized Modulus in Light of ACT and SPT Data

Waqas Ahmed, Constantinos Pallis, Mansoor Ur Rehman

We analyze a generalized framework of smooth F-term hybrid inflation (smFHI) consistent with gauge coupling unification within the Minimal Supersymmetric Standard Model (MSSM). The…

Inflation, Proton Decay and Gravitational Waves from Metastable Strings in $S U (4)_{C} \times S U (2)_{L} \times U (1)_{R}$ Model

Waqas Ahmed, Maria Mehmood, Mansoor Ur Rehman +1

We present a realistic supersymmetric $μ$ -hybrid inflation model within the framework of $S U (4)_{C} \times S U (2)_{L} \times U (1)_{R}$ gauge symmetry, wherein the symmetry breaking $SU(4)…

Supersymmetric Hybrid Inflation in Light of CMB Experiments and Swampland Conjectures

Waqas Ahmed, Shabbar Raza

This study revisits supersymmetric (SUSY) hybrid inflation in light of CMB experiments and swampland conjectures. We first show that if one adds radiative, soft mass, and SUGRA cor…

Probing Stochastic Gravitational Wave Background from $S U (5) \times U (1)_{χ}$ Strings in Light of NANOGrav 15-Year Data

Waqas Ahmed, Mansoor Ur Rehman, Umer Zubair

A realistic model of $S U (5) \times U (1)_{χ}$ , embedded in $S O (10)$ supersymmetric grand unified theory, is investigated for the emergence of a metastable cosmic string network. This…

LHC Run-3, $b - τ$ Yukawa Unification and Dark Matter Implications in SUSY 4-2-2 model

Waqas Ahmed, Mohamed Belfkir, Salah Nasri +2

We revisit the bottom and $τ$ Yukawa coupling unification in supersymmetric $4$ - $2$ - $2$ model and present for the first time the sbottom-neutralino co-annihilation scenario consist…
