We present the results of a search for associated production
of the chargino and neutralino supersymmetric particles using up to
1.1 fb-1 of integrated luminosity collected by the CDF II experiment at
the Tevatron p anti-p collider at a center-of-mass energy of 1.96 TeV.
The search is conducted by analyzing events with a large transverse
momentum imbalance and either three charged leptons or two charged leptons
of the same electric charge. The numbers of observed events are found
to be consistent with standard model expectations. Upper limits on the
production cross section are derived in different theoretical models.
In one of these models a lower limit on the mass of the chargino is set
at 129 GeV/c2 at the 95% confidence level.
