Relics of the Cosmological QCD Phase Transition

High Energy Physics - Phenomenology 2009-10-31 v2

Abstract

The abundance and size distribution of quark nuggets (QN), formed a few microseconds after the big bang due to first order QCD phase transition in the early universe, has been estimated. It appears that stable QNs could be a viable candidate for cosmological dark matter. The evolution of baryon inhomogeneity due to evaporated (unstable) QNs are also examined.
