标题： Big-bang nucleosynthesis with a long-lived CHAMP including He4 spallation process

摘要： 我们提出在超对称标准模型中由长寿命的stau引发的氦-4散裂过程，并研究这些过程对轻元素丰度的影响。 我们表明，只要氦-4散裂过程的相空间是开放的，它们就比stau催化融合更重要，因此限制了stau的特性。 本报告基于以下工作 (Jittoh 等，2011). 显示英文摘要

摘要： We propose helium-4 spallation processes induced by long-lived stau in supersymmetric standard models, and investigate an impact of the processes on light elements abundances. We show that, as long as the phase space of helium-4 spallation processes is open, they are more important than stau-catalyzed fusion and hence constrain the stau property. This talk is based on works (Jittoh et al., 2011).
