| 内容記述 | Big bang nucleosynthesis is reviewed with taking into account the observed abundance of light elements. We examine the standard big bang nucleosynthesis (SBBN) and confirm that helium abundance is not enough to fix the baryon to photon ratio η.As for deuterium, observational constraint on η agrees well with the value determined from WMAP. It is, however, difficult to reconcile the observations of ^7Li with the WMAP constraint. Furthermore, we investigate a simple two-zone model of inhomogeneous big bang nucleosynthesis (IBBN), where we review a series of our recent studies. In a high density region, heavy elements are produced up to the mass number 160. We present several interesting results that may become an important milestone for the origin of the elements in the universe. | |||||
