Title: Supersymmetric and smooth hybrid inflation in the light of WMAP3

Abstract

In their minimal form both supersymmetric and smooth hybrid inflation yield a scalar spectral index n{sub s} close to 0.98, to be contrasted with the result n{sub s}=0.951{sub -0.019}{sup +0.015} from WMAP3. To realize better agreement, following Bastero-Gil, King, and Shafi, we extend the parameter space of these models by employing a nonminimal Kaehler potential. We also discuss nonthermal leptogenesis by inflaton decay and obtain new bounds in these models on the reheat temperature to explain the observed baryon asymmetr000.
