Searches for supersymmetric particles have been performed using these data samples. The results from the four LEP experiments have been combined. Model independent limits on the pair-production cross-sections of supersymmetric particles and constraints on their masses are presented in the context of the Minimal Supersymmetric Standard Model (MSSM) and in the context of gauge-mediated supersymmetry breaking models (GMSB). Results assuming an R-parity violating scenario are also reviewed.4 pages, 6 figures, Proceedings of Moriond 03 - QCD weekHigh Energy Physics - Experimenttext
