Search for chargino-neutralino production in pp-bar collisons at sqrt s=1.8 TeV. Academic Article uri icon

abstract

  • We have searched for chargino-neutralino production (102) in 1.8 TeV pp collisions, followed by their leptonic decays 1 01 and 0201+-. These trilepton events are expected within a framework of the minimal supersymmetric standard model (MSSM). In a 19.1pb-1 data sample collected with a Collider Detector at Fermilab, no trilepton events were observed. Upper limits on (pp 102)BR(1023 + X) were obtained for various MSSM parameter space regions, yielding new 95% confidence level lower limits for the neutralino (02) mass which extend as high as 49GeV/c2. 1996 The American Physical Society.
