abstract
In theories with gauge-mediated supersymmetry breaking, the scalar [Formula presented], [Formula presented] is the lightest observable superpartner for part of the parameter space. At CERN LEP 2, the production of such a [Formula presented] pair and their subsequent decays give rise to a pair of [Formula presented] leptons plus missing energy from the unobserved gravitinos. The angular distributions of the [Formula presented]s are different from those arising from the production and decay of [Formula presented] pairs, and thus will constitute an interesting signal for supersymmetry. We also consider [Formula presented] pair production in the complementary part of parameter space where the lightest neutralino is lighter than the [Formula presented]. 1997 The American Physical Society.
