Search for chargino-neutralino production in ${p\bar{p}}$ collisions at
$\sqrt s$ = 1.96 TeV with high-$p_T$ leptons
We present a search for the associated production of charginos and neutralinos in $\rm {p \bar p}$ collisions at $\sqrt{s}$ = 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-\pt\ 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 MSSM scenario with no slepton mixing we set a 95\% C.L. limit at 151 GeV/$c^2$. © 2008 The American Physical Society.
