-Symmetry Breaking in Supersymmetric Hybrid Inflation
Matthew Civiletti, Mansoor Ur Rehman, Eric Sabo +2
We consider a supersymmetric hybrid inflation scenario in which the U(1) -symmetry is explicitly broken by Planck scale suppressed operators in the superpotential. We provide an…
Red Spectral Tilt and Observable Gravity Waves in Shifted Hybrid Inflation
Matthew Civiletti, Mansoor Ur Rehman, Qaisar Shafi +1
We consider supersymmetric shifted hybrid inflation models with a red tilted scalar spectral index n_s in agreement with the WMAP 7-yr central value. If non-minimal supergravity co…
Observable Gravity Waves from Supersymmetric Hybrid Inflation II
Mansoor Ur Rehman, Qaisar Shafi, Joshua R. Wickman
It is shown that a tensor-to-scalar ratio close to r = 0.03, which can be observed by Planck, is realized in supersymmetric hybrid inflation models with TeV-scale soft supersymmetr…
Observable Gravity Waves From Supersymmetric Hybrid Inflation
Qaisar Shafi, Joshua R. Wickman
We identify models of supersymmetric hybrid inflation in which the tensor-to-scalar ratio, a canonical measure of gravity waves produced during inflation, can be as large as 0.03 o…
Minimal Supersymmetric Hybrid Inflation, Flipped SU(5) and Proton Decay
Mansoor Ur Rehman, Qaisar Shafi, Joshua R. Wickman
Minimal supersymmetric hybrid inflation utilizes a canonical Kahler potential and a renormalizable superpotential which is uniquely determined by imposing a U(1) R-symmetry. In com…
Supersymmetric Hybrid Inflation Redux
Mansoor Ur Rehman, Qaisar Shafi, Joshua R. Wickman
We discuss the important role played during inflation by one of the soft supersymmetry breaking terms in the inflationary potential of supersymmetric hybrid inflation models. With…
