The allowed range of parameters for supersymmetric hybrid inflation and its extensions are investigated. The lower bound on the reheat temperature T_r in these models with hierarchical right handed neutrinos is found to be 3*10^7 GeV. (T_r as low as 100 GeV is possible for quasi degenerate right handed neutrinos.) We also present revised estimates for the scalar spectral index and the symmetry breaking scale associated with inflation.

  1. Shifted Hybrid Realization of Non-Minimal Higgs Inflation in Light of ACT DR6 and Planck Data

    hep-ph 2026-07 conditional novelty 4.0

    A shifted-hybrid non-minimal Higgs inflation model deforms the Starobinsky attractor via a leading non-renormalizable superpotential operator to raise ns into the ACT-preferred range while keeping r ~ 10^{-3}-10^{-2}.

    hep-ph 2026-05 unverdicted novelty 4.0

    F-term hybrid inflation with SU(1,1)/U(1) or SU(2)/U(1) Kähler geometry in GUTs can be realized without inflationary extrema for broad parameters, matching ACT/SPT data via curvature and tadpole adjustments while pred...
