A gluino can decay into a color-singlet neutral fermion [Formula: see text] by radiating off a gluon. We study this process in a minimal supersymmetric extension of the standard model. A significant branching fraction is possible depending on how much [Formula: see text] overlaps with the Higgs fermion which couples to the t quark and the mass of the t quark itself.
