# WMAP and inflation

@article{Barger2003WMAPAI, title={WMAP and inflation}, author={Vernon Barger and Hye-Sung Lee and Danny Marfatia}, journal={Physics Letters B}, year={2003}, volume={565}, pages={33-41} }

Abstract We assay how inflationary models whose properties are dominated by the dynamics of a single scalar field are constrained by cosmic microwave background (CMB) data from the Wilkinson Microwave Anisotropy Probe (WMAP). We classify inflationary models in a plane defined by the horizon-flow parameters. Our approach differs from that of the WMAP Collaboration in that we analyze only WMAP data and take the spectral shapes from slow-roll inflation rather than power-law parameterizations of…
