Search for SUSY at Tevatron Run II from Chargino-Neutralino Production in Low $P_t$ Di-muon Channel

The Minimal Supersymetric Standard Model (MSSM) predicts the production of tri-lepton events at the Tevatron via chargino-neutralino production. We will present our sensitivity for discovering this production using low $p_t$ di-muon data. We use a dataset corresponding to an integrated luminosity of about 270 pb$^{-1}$ taken by the CDF-II detector during Run II of the Tevatron, which is more than twice the data collected in Run I of Tevatron.
