Dynamics of the Cosmological Quark-Hadron Transition in a Matter Dominated Universe: Distribution and Evolution of Baryon Inhomogeneities
Abstract
We study the dynamics of the quark-hadron transition for a scenario in which the Universe is matter dominated and a large amount of entropy is generated by decaying particles of mass 1--10 TeV, as suggested by a large class of superstring--inspired models. We estimate the nucleation rate and compute the mean separation between baryon fluctuations generated during the transition following their evolution up to the onset of primordial nucleosyntheisis.
