Red Spectral Tilt and Observable Gravity Waves in Shifted Hybrid Inflation
Abstract
We consider supersymmetric shifted hybrid inflation models with a red tilted scalar spectral index ns in agreement with the WMAP 7-yr central value. If non-minimal supergravity corrections are included, these models can also support a tensor-to-scalar ratio as large as r = 0.02, which may be observable by the Planck Satellite. In contrast to the standard supersymmetric hybrid inflation scenario, topological defects produced via gauge symmetry breaking are inflated away in the shifted version of the theory.
