Hybrid Inflation in Quasi-minimal Supergravity with Monotonic Inflationary Potentia

Abstract

We show how supersymmetric hybrid inflation with scalar spectral index $n_{\mathrm{s}}\simeq 0.96-0.97$ is realized in the context of quasi-minimal supergravity if we insist that the inflationary potential not exhibit any local minima. We also address the problem of the initial conditions for both monotonic and non-monotonic inflationary potentials.
