The result of a search for gaugino pair production with a trilepton signature is reinterpreted in the framework of minimal supergravity (MSUGRA) with R-parity violation via leptonic λ Yukawa couplings. The search used 95 pb−1 of p¯p collisions at √s=1.8TeV recorded by the DØ detector at the Fermilab Tevatron. A large domain of the MSUGRA parameter space is excluded for λ121, λ122>~10−4.
