Abstract

We present constraints on canonical single-field inflation derived from WMAP five year, ACBAR, QUAD, BICEP data combined with the halo power spectrum from SDSS LRG7. Models with a non-scale-invariant spectrum and a red tilt n(S) < 1 are now preferred over the Harrison-Zel'dovich model (n(S) = 1, tensor-to-scalar ratio r = 0) at high signi...More
