Big-bang nucleosynthesis with a long-lived CHAMP including He4 spallation process
Abstract content
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.
