Search for Supersymmetry in p\overline{p} Collisions at \sqrt{s} =1.96 TeV Using the Trilepton Signature of Chargino-Neutralino Production

The production of chargino-neutralino pairs and their subsequent leptonic decays is one of the most promising supersymmetry (SUSY) signatures at the Tevatron $p\bar{p}$ collider. We present here the most recent results on the search for the three-lepton and missing-transverse-energy SUSY signature using data collected with the CDF II detector. The results are interpreted within the minimal supergravity (mSugra) scenario.
