Search for Trilepton Signatures from Associated Gaugino Pair Production

We report on a search for the trilepton decay signature from the associated production of supersymmetric gaugino pairs, ${\tilde{\chi }}_1^{\pm }{\tilde{\chi }}_2^0$, within the context of minimal supersymmetric models that conserve $R$ parity. This search uses $95{\mathrm{pb}}^{-1\mathrm{}}$ of $p\overline{p}$ data taken at $\sqrt{s}=1.8\mathrm{}\mathrm{TeV}$ 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 ${\tilde{\chi }}_1^{\pm }$ mass.
