Big bang nucleosynthesis: A status report

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

A status report on the standard model of big bang nucleosynthesis (BBN) in the post-WMAP era is presented. With the value of the baryon-to-photon ratio determine to relatively high precision by WMAP, standard BBN no longer has any free parameters. In this context, the theoretical prediction for the abundances of D, He4, and Li7 is discussed and compared to the observational determination of the light nuclides. While concordance for D and He4 are satisfactory, the prediction for Li7 exceeds the observational determination by a factor of about four. Possible solutions to this problem are also discussed.
