| アブストラクト: |
Long-lived charged massive particle (CHAMP) plays a role as catalyzer of exotic nuclear reactions in the Big-bang nucleosynthesis era. I discuss the primordial abundances of light elements involving the helium-4 spallation processes, the catalyzed fusion processes, and the internal conversion processes. Furthermore, I show the cosmologically favored parameter space in the minimal supersymmetric standard model with long-lived stau via solving the Lithium-7 problem. |
