MSSM, Msugra and the LSP at LEPII

More than one year after the end of LEPII, many analysis activities are still going on to translate the negative search results of the four LEP experiments into solid limits on cross-sections and masses of SUSY particles. Many analyses based on the MSSM and Msugra models are presented in this paper. Preliminary results including the limit on the mass of the lightest supersymmetric particle (LSP) within the RP conservation hypothesis are also given.
