Search for Supersymmetry in Trilepton Final States with the DO Detector

Abstract

Data taken by the DO experiment at the proton-antiproton collider at Tevatron has been analyzed to search for signatures consistent with decay of charginos and neutralinos. The search is performed in final states with three leptons and missing transverse energy. No excess above the standard model expectation is observed and limits on the production cross section times branching fraction are set.
