SEARCH FOR W1Z2 PRODUCTION VIA TRILEPTON FINAL STATES IN PP COLLISIONS AT S = 1.8 TEV

We have searched for associated production of the lightest charginoW 1 and next-to-lightest neutralinoZ 2 of the minimal supersymmetric standard modelin pp collisions at √s=1.8 TeV using the D0 detector at the Fermilab Tevatroncollider. Data corresponding to an integrated luminosity of 12.5±0.7pb -1 were examined for events containing three isolated leptons. No evidence for W 1 Z 2 pair productionwas found. Limits on s(W 1 Z 2 )B(W 1 →lνZ 1 )B(Z 2 →llZ 1 ) are presented.
