摘要：
We investigate primordial nucleosynthesis in a Brans-Dicke model with a decaying A term using the Monte-Carlo method and likelihood analysis. The produced abundances of He-4 and D are consistent with the observations when the baryon to photon ratio eta(10) = 5.47 - 6.64, which is in agreement with the value deduced from WMAP.
