Nucleosynthesis in a baryon-inhomogeneous universe with coupled baryon diffusion

Conference ·
OSTI ID:6507099
Detailed calculations of big-bang nucleosynthesis in baryon-inhomogeneous universes show that {Omega}{sub b} can be considerably larger than its limit from standard big-bang nucleosynthesis. Such results require that late-time hydrodynamic effects deplete overproduction of {sup 7}Li and that the QCD surface tension be near the cube of the QCD coexistence temperature for fluctuations of the correct length scales to arise. 15 refs., 1 fig.
