Fitting BOOMERANG and MAXIMA-1 data with a Einstein-Yang-Mills Cosmological Model

Abstract

We analyse the implications of recent Cosmic Microwave Background (CMB) data for a specific cosmological model, based on the higher-dimensional Einstein-Yang-Mills System compactified on a $R\times S^3\times S^d$ topology and conclude that the model parameters are tightly constrained by CMB spectra. Moreover, the model predicts a relationship between the deceleration parameter at present, $q_0$, and some characteristic features of CMB spectra, namely the height of the first peak and the location of the second peak, that is consistent with the observations and which can be further tested by future CMB and other experiments.
