Search for R-Parity Violating SuperSymmetry in the Four-Lepton Final State at the Tevatron

Assuming a long lifetime for the lightest supersymmetric particle and R-parity violation, a scenario can be constructed where four or more leptons are present in the final state in proton-antiproton collisions at $\sqrt{s}$ 1.96 TeV at the Tevatron. We investigate the sensitivity of this signature in the minimal supergravity framework and compare it to standard model predictions. A blind analysis is done on 300 pb$^{-1}$ of data collected by the CDF detector and is used to constrain the SUSY parameter space.
