Limit on the Associated Production of Charginos and Neutralinos in ppbar collisions at $\sqrt{s}=1.96$ TeV

ORAL

Abstract

We search for the associated production of charginos and neutralions in ppbar collisions at $\sqrt{s}=1.96$ TeV measured with the CDF experiment at the Fermilab Tevatron. The results are obtained from high-pt and medium-pt lepton triggers, using channels with three leptons and two like-sign leptons, with $\sim$350 pb$^{-1}$ of data. Limits on the production time branching ratio as well as excluded region in the minimal supergravity SUSY framework are presented.
