KEK素粒子原子核研究所・理論セミナー（大河内 豊 准教授）
概要
In this talk, I will discuss the decay of metastable de Sitter vacua catalyzed by a black hole and a cloud of strings and apply the method to the creation of the four dimensional bubble universe in the five dimensional AdS spacetime. We study the bounce action for the creation and find that the bubble with very small cosmological constant is favored by the catalysis by assuming appropriate mass scales of the black hole and the cloud of strings to reproduce the present energy densities of matter and radiation in the bubble universe.
