We use the three lepton and missing energy "trilepton"
signature to search for chargino-neutralino production with 2.0 fb-1 of
integrated luminosity collected by the CDF II experiment at the Tevatron
p anti-p collider. We expect approximately 11 supersymmetric events for a
specific choice of parameters of the mSUGRA model, but our observation of
7 events is consistent with the standard model expectation of 6.4 events.
We constrain the mSUGRA model of supersymmetry and rule out chargino
masses up to 145 GeV/c2 for a specific choice of parameters.
