Abstract

>We present new cosmological constraints on single-field inflation in light of the Wilkinson Microwave Anisotropy Probe satellite mission five-year results (WMAP5). We find that the cosmic microwave background data are quite consistent with a Harrison-Zel'dovich primordial spectrum with no running and zero tensor amplitude.
