Abstract:We investigate the viability of inflation with a spectator sector comprised of non-Abelian gauge fields coupled through a higher order operator. We dub this model "spectator Gaugeflation". We study the predictions for the amplitude and tensor tilt of chiral gravitational waves and conclude that a slightly red-tilded tensor power spectrum is preferredAs with related models, the enhancement of chiral gravitational waves with respect to the single-field vacuum gravitational wave background is controlled by the pa… Show more
