| dc.description | We consider constraints on long-lived charged scalar leptons \tilde{l}^\pm in supersymmetric models, where gravitino is the lightest superparticle. We study the decay and hadronization processes of \tilde{l}^\pm. We also take into account the significant enhancement of Li6 production due to the formation of the bound-state (He4 \tilde{l}^-); for this purpose, we use the reaction rate given by the most recent calculation based on coupled-channel method. | |
