Gravitational waves in an anomaly-induced inflation

High Energy Physics - Phenomenology 2009-11-10 v1

Abstract

The behaviour of gravitational waves in the anomaly-induced inflationary phase is studied. The metric perturbations exhibit a stable behaviour, with a very moderate growth in the amplitude of the waves. The spectral indice is computed, revealing an almost flat spectrum.
