Sumario:The search for the production of scalar leptons at LEP is presented. The results indicate that the data are in agreement with standard model predictions. A follow up to the reported excess of stau candidates in the 1999 LEP data is presented. It was found that there was no coherent excess of stau candidates from data collected in 2000. In the absence of a signal, limits have been placed on the mass of the sleptons based on a 95% CL exclusion. The selectron mass has been excluded up to 99.4 GeV/c/sup 2/ for a chi /sub 1//sup 0/ mass of 40 GeV/c/sup 2/. Similarly, the smuon mass has been excluded to 95.4 GeV/c/sup 2/ and the stau mass has been excluded to 85.4 GeV/c /sup 2/. (6 refs).
