Search for the Trilepton Signature from the Associated Production of SUSY Chi_1^(+-) Chi_2^0 Gauginos

Abstract

We report on a search for the trilepton signature from the associated production of supersymmetric gaugino pairs, Chi_1^(+-) Chi_2^0, within the context of minimal supersymmetric models that conserve R-parity. This search uses 95 pb^-1 of data taken with the \D0 detector at Fermilab's Tevatron collider at \sqrt{s} = 1.8 TeV. No evidence of a trilepton signature has been found, and a limit on the production cross section times branching fraction to trileptons as a function of Chi_1^(+-) mass is given.
