Gravitational waves in an anomaly-induced inflation

arXiv:hep-ph/0311309 · doi:10.1016/S0920-5632(03)02421-6

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.
