- 論文の詳細を見る
Primordial uncleosynthesis in a ``cold'' universe is investigated for wide ranges of both the initial baryon/photon ration, 3×10^<-6>≦η_i≦15, and lepton/baryon ratio, 1≦Le/B≦10^5. Constraints on these parameters are obtained from the abundance of heavy elements. Most importantly, cold universe models with a baryon/photon ratio η_i>10^<-4> can be ruled out.
