Recently observed anomalous events at the CERN Panti-P collider could be the first evidence for supersymmetry. The authors study this possibility by evaluating the production and decay mechanisms for heavy squarks and/or gluinos with a minimal supersymmetric extension of the standard model. The predictions of several distinct scenarios are compared with the currently available data, and it is shown how these data impose mass limits on the supersymmetric particles. A scenario involving a light gluino is also introduced and studied. It is shown that this scenario reproduces certain aspects of the data more naturally than competing scenarios. Technical refinements to the scenario including soft fragmentation and the presence of gluinos in the initial nucleon are introduced and studied. Difficulties with the light gluino model are also discussed. A general summary of the current experimental situation and its implications for supersymmetry is presented. Four appendices present technical details of the analyses.
