Description
We consider constraints on long-lived charged scalar leptons l-tilde± in supersymmetric models, where gravitino is the lightest superparticle. We study the decay and hadronization processes of l-tilde±. We also take into account the significant enhancement of 6L production due to the formation of the bound-state (He4l-tilde-); for this purpose, we use the reaction rate given by the most recent calculation based on coupled-channel method
