Search for chargino-neutralino production in p(p)over-bar collisions at root s=1.96 TeV with high-p(T) leptons

We present a search for the associated production of charginos and neutralinos in p (p) over bar collisions at root s = 1.96 TeV. The data were collected at the Collider Detector at Fermilab (CDF II) and correspond to integrated luminosities between 0.7 and 1.0 fb(-1). We look for final states with one high-p(T) electron or muon, and two additional leptons. Our results are consistent with the standard model expectations, and we set limits on the cross section as a function of the chargino mass in three different supersymmetric scenarios. For a specific minimal supersymmetric standard model scenario with no slepton mixing, we set a 95% C. L. limit at 151 GeV/c(2).
