Deuterium and Li7 Concordance in Inhomogeneous Big Bang Nucleosynthesis Models

Recent observational constraints on primodial deuterium and Li7 correspond to different values of the baryon-to-photon ratio when applied to the Standard Big Bang Nucleosynthesis (SBBN) model. In this article these constraints are applied to baryon Inhomogeneous (IBBN) models. A depletion factor of 3.4 applied to the Li7 constraints will bring Li7, deuterium and He4 constraints in concordance for both the SBBN and IBBN models. A depletion factor of 6.1 will bring concordance for the IBBN model alone
