Search for Trilepton Signatures from Associated Gaugino Pair Production

Abstract

We report on a search for the trilepton decay signature from the associated production of supersymmetric gaugino pairs, {tilde {chi}}{sup {plus_minus}}{sub 1}{tilde {chi}}{sub 2}{sup 0}, within the context of minimal supersymmetric models that conserve R parity. This search uses 95 pb{sup {minus}1} of p{bar p} data taken at {radical}(s)=1.8 TeV with the D0 detector. No evidence of a trilepton signature has been found, and a limit on the product of cross section times branching fraction to trileptons is given as a function of {tilde {chi}}{sup {plus_minus}}{sub 1} mass. {copyright} {ital 1998} {ital The American Physical Society}
