Findings

New lower mass limits for the lightest neutralino

Extended search results for sfermions, charginos, and neutralinos

Constraints on the MSSM parameter space

Abstract

In the final run in the year 2000 the four experiments at the electron positron collider LEP have accumulated data corresponding to an integrated luminosity of more than 210 pb-1 per experiment at centre-of-mass energies up to 208 GeV. These data have been used to extend the search for supersymmetric particles in the new energy domain. In the present paper the results of searches for sfermions, charginos and neutralinos are described, assuming the minimal supersymmetric standard model with R-parity conservation. In addition, the determination of a lower mass limit of the lightest neutralino is discussed.
