Gravitational Waves from New Inflation
Abstract
Gravitational waves provide one of the most powerful observational probes for discriminating among inflationary models. In particular, it has recently become clear that the high-frequency gravitational-wave spectrum encodes a wealth of information about the properties of the inflaton and the post-inflationary dynamics. In this paper, we present the first comprehensive prediction of the complete gravitational-wave spectrum in the new inflation scenario, a prototypical realization of small-field inflation, incorporating all known production mechanisms including both the classical and quantum sources.
