The search is divided into three-lepton and four-or-more-lepton data samples. We observe six events in the three-lepton sample and zero events in the ≥4-lepton sample. Both numbers of events are consistent with standard model background expectations. Within the framework of an R-parity-violating supergravity model, the results are interpreted as mass limits on the lightest neutralino (χ10) and chargino (χ1±) particles. For one particular choice of model parameters, the limits are M(χ10)>110  GeV/c2 and M(χ1±)>203   GeV/c2 at 95% confidence level; the variation of these mass limits with model parameters is presented.
