Mutated Hybrid Inflation

Astrophysics 2009-10-22 v2 High Energy Physics - Phenomenology

Abstract

A new model of inflation is described. An unusual form for the inflationary potential is obtained because the inflaton corresponds to a non-trivial path in the configuration space of the two real scalar fields of the model. The model predicts a spectral index n=13/2N0.97n = 1 - 3/2N \simeq 0.97 for the density perturbations and negligible gravitational waves.
