Coupled baryon diffusion and nucleosynthesis in the early universe
Description
Detailed calculations of big-bang nucleosynthesis in baryon-inhomogeneous universes show that Ωb can be considerably larger than its limit from standard big-bang nucleosynthesis. such results require that late-time hydrodynamic effects deplete overproduction of 7Li and that the QCD surface tension be near the cube of the QCD coexistence temperature for fluctuations of the correct length scales to arise.
