### Abstract

An update on the standard model of big bang nucleosynthesis (BBN) is presented. With the value of the baryon-tophoton ratio determined to high precision by WMAP, standard BBN is a parameter-free theory. In this context, the theoretical prediction for the abundances of D, ^{4}He, and ^{7}Li is discussed and compared to their observational determination. While concordance for D and ^{4}He is satisfactory, the prediction for ^{7}Li exceeds the observational determination by a factor of about four. Possible solutions to this problem are discussed.
