摘要：

The quark-hadron phase transition in the early universe can produce inhomogeneities in the distribution of nucleons, which in tum affect the primordial nucleosynthesis. In all the investigations of this problem it has been assumed that the degree of super-cooling of the quark-gluon plasma after the phase transition is large enough to produce a significant rate of nucleation of hadrons. Using the latest results of finite-temperature lattice QCD and the finite-size scaling theory, we argue that the degree of supercooling is in fact extremely small and hence the nucleation rate is negligible.
