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 nucleatio n rate and compute the mean separation between baryon fluctuations gen erated during the transition following their evolution up to the onset of primordial nucleosynthesis.
