| Summary: | A search for trileptonic final states from the Wino-Zino associated production has been performed with the DO Detector at the Fermi National Accelerator Laboratory (Fermilab) Tevatron at a center-of-mass energy of 1.8 TeV. Leptons included in the analysis are limited to electrons and muons, defining four different channels : eee, ee[], e[], and []. Based on approximately 95 pb-1 of data in each channel, no candidate event is found. Assuming R-parity conservation and mass relationships : [ ], this null result is translated into an upper limit of Wino-Zino production times the branching fraction to any of the trileptonic final states as a function of M[]. This limit ranges from 0.7 pb for M[]= 45 GeV/C2 to 0.1 pb for M[]= 124 GeV/ C2 . A study to extend the application 1 of this limit using more general assumptions will be discussed. |
