Book excerpt: A search for gaugino pair production with a trilepton signature in the framework of R-parity violating supersymmetry via the couplings ?121, ?122, or ?133 is presented. The data, corresponding to an integrated luminosity of L ≈ 360 pb−1, were collected from April 2002 to August 2004 with the D0 detector at the Fermilab Tevatron Collider, at a center-of-mass energy of √s = 1.96 TeV. This analysis considers final states with three charged leptons with the flavor combinations eel, ??l, and ee? (l = e or ?). No evidence for supersymmetry is found and limits at the 95% confidence level are set on the gaugino pair production cross section and lower bounds on the masses of the lightest neutralino and chargino are derived in two supersymmetric models.
