Sneutrino Tribrid Inflation in Flipped : Confronting ACT DR6 and Planck
Farishta Israr, Mansoor Ur Rehman, Saleh O. Allehabi
We construct a realization of sneutrino tribrid inflation within the -symmetric flipped grand unified theory. A vector-like pair of matter multiplets, $10_V+\overline{10…
Shifted Hybrid Realization of Non-Minimal Higgs Inflation in Light of ACT DR6 and Planck Data
Nadir Ijaz, Pirzada, Mansoor Ur Rehman
We investigate non-minimal Higgs inflation in a no-scale-inspired supergravity framework and confront its predictions with the latest CMB constraints from ACT DR6 and \emph{Planck}…
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…
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…
Radiatively Corrected Hybrid Inflation: Parameter Scans and Machine Learning with ACT and Future CMB Experiments
Waqas Ahmed, Saleh O. Allehabi, Mansoor Ur Rehman
We investigate a realistic non-supersymmetric hybrid inflation model incorporating right-handed neutrinos and assess its viability in light of recent cosmological observations. At…
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,,…
