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…

Revisiting Polynomial Hybrid Inflation: Planck and ACT Compatibility via Radiative Corrections

Waqas Ahmed, Saleh O. Allehabi, Mansoor Ur Rehman

We investigate the impact of one-loop radiative corrections in a non-supersymmetric model of hybrid inflation with a chaotic (polynomial-like) potential, $V (ϕ) = V_{0} + λ_{p} ϕ^{p}$ , in…

Tribrid Inflation, Type II Leptogenesis, and Observable Gravitational Waves in $S U (3)_{c} \times S U (2)_{L} \times S U (2)_{R} \times U (1)_{B - L}$

Waqas Ahmed, Saleh O. Allehabi, Farishta Israr +1

We present a concrete realization of tribrid inflation within the framework of the gauge group $S U (3)_{c} \times S U (2)_{L} \times S U (2)_{R} \times U (1)_{B - L}$ . In this model, inflation i…
