Big-Bang Nucleosynthesis with Long-Lived Charged Slepton
Abstract
We consider constraints on long-lived charged scalar leptons l in supersymmetric models, where gravitino is the lightest superparticle. We study the decay and hadronization processes of l. We also take into account the significant enhancement of Li6 production due to the formation of the bound-state (He4 l-); for this purpose, we use the reaction rate given by the most recent calculation based on coupled-channel method.
