Very long-lived Stop NLSP in MSSM scenarios with Gravitino LSP

J. Lorenzo Diaz-Cruz, Bryan O. Larios

We present the calculation of the stop ($\tilde{t}$) lifetime that results from its decay into gravitinos (${\tilde{\Psi }}^{\mu }$) in the final state, namely $\tilde{t}\to {\tilde{\Psi }}^{\mu }+X$, whe…
