Predictions of quantum gravity in inflationary cosmology: effects of the Weyl-squared term
Abstract We derive the predictions of quantum gravity with fakeons on the amplitudes and spectral indices of the scalar and tensor fluctuations in inflationary cosmology. The action is R +R 2 plus the Weyl-squared term. The ghost is eliminated by turning it into a fakeon, that is to say a purely vir...
