A dark radiation era prior to the inflationary phase
arXiv:0901.2488 · doi:10.1016/j.physletb.2009.01.008
Abstract
A cosmological model dominated at the beginning by a dark radiation followed by a period of inflation is presented. This model is based on a Randall-Sundrum II type brane-world. Current observational data are used to fix the parameters associated to the dark radiation.
