We compare the simplest realistic brane inflationary model to recent cosmological data, including WMAP 3-year cosmic microwave background (CMB) results, Sloan Digital Sky Survey luminous red galaxies (SDSS LRG) power spectrum data and Supernovae Legacy Survey (SNLS) Type 1a supernovae distance measures. Here, the inflaton is simply the position of a D3-brane which is moving towards a D̄3-brane sitting at the bottom of a throat (a warped, deformed conifold) in the flux compactified bulk in Type… CONTINUE READING
