22 Jul 1993 | Journal: | Phys.Rev. D50 (1994) 4881-4885 | Subject: | astro-ph hep-lat | Abstract: | We review recent lattice QCD results for the surface tension at the finite temperature quark-hadron phase transition and discuss their implications on the possible scale of inhomogeneities. In the quenched approximation the average distance between nucleating centers is smaller than the diffusion length of a protron, so that inhomogeneities are washed out by the time nucleosynthesis sets in. Consequently the baryon density fluctuations formed by a QCD phase transition in the early universe cannot significantly affect standard big-bang nucleosynthesis calculations and certainly cannot allow baryons to close the universe. At present lattice results are inconclusive when dynamical fermions are included. | Source: | arXiv, astro-ph/9307031 | Services: | Forum | Review | PDF | Favorites |
