LARGE-SCALE INHOMOGENEITIES FROM THE QCD PHASE-TRANSITION

We examine the first-order cosmological QCD phase transition for a lar ge class of parameter values, previously considered unlikely. We find that the hadron bubbles can nucleate at very large distance scales, th ey can grow as detonations as well as deflagrations, and that the phas e transition may be completed without reheating to the critical temper ature. For a subset of the parameter values studied, the inhomogeneiti es generated at the QCD phase transition might have a noticeable effec t on nucleosynthesis.
