Search for Chargino-Neutralino Pair Production at CDF

Abstract

We present the results of a search for associated production of the lightest chargino and next-to-lightest neutralino using 1 fb$^{-1}$ of $\sqrt s$ = 1.96 TeV p$\rm \bar p$ data collected with the CDF detector at the Tevatron. We combine the results of several multi-lepton final states to set upper limits on the cross section times branching ratio for chargino-neutralino production as a function of the chargino mass.
