Abstract: (Elsevier)

We have performed a search for supersymmetric particles using acoplanar pairs of oppositely-charged particles in decays of the Z 0 . In 0.53 pb −1 of integrated luminosity near the Z 0 peak, we observe two events where approximately four are expected from background, allowing limits to be extended on combined photino and slepton masses, and also on combined photino and chargino masses.
