Radiative gravitino decays from R-parity violation
We study radiative gravitino decay within the framework of R-violating supersymmetry. For trilinear R-violating couplings that involve the third generation of fermions, or for light gravitinos, we find that the radiative loop-decay $\tilde{G} \to \gamma \nu$ dominates over the tree-level ones for a...
