Gravity Waves From Non-Minimal Quadratic Inflation
Constantinos Pallis, Qaisar Shafi
We discuss non-minimal quadratic inflation in supersymmetric (SUSY) and non-SUSY models which entails a linear coupling of the inflaton to gravity. Imposing a lower bound on the pa…
Reconciling Induced-Gravity Inflation in Supergravity With The Planck 2013 & BICEP2 Results
C. Pallis
We generalize the embedding of induced-gravity inflation beyond the no-scale Supergravity presented in arXiv:1403.5486 employing two gauge singlet chiral superfields, a superpotent…
From Hybrid to Quadratic Inflation With High-Scale Supersymmetry Breaking
Constantinos Pallis, Qaisar Shafi
Motivated by the reported discovery of inflationary gravity waves by the BICEP2 experiment, we propose an inflationary scenario in supergravity, based on the standard superpotentia…
Induced-Gravity Inflation in no-Scale Supergravity and Beyond
C. Pallis
Supersymmetric versions of induced-gravity inflation are formulated within Supergravity (SUGRA) employing two gauge singlet chiral superfields. The proposed superpotential is uniqu…
Upper Bound on the Tensor-to-Scalar Ratio in GUT-Scale Supersymmetric Hybrid Inflation
Matthew Civiletti, Constantinos Pallis, Qaisar Shafi
We explore the upper bound on the tensor-to-scalar ratio in supersymmetric (F-term) hybrid inflation models with the gauge symmetry breaking scale set equal to the value $2.86\…
