We present a search for chargino-neutralino associated
production using like electric charge dilepton events collected by the CDF
II detector at the Fermilab Tevatron in proton-antiproton collisions at
sqrt (s) = 1.96 TeV. One lepton is identified as the hadronic decay of a
tau lepton, while the other is an electron or muon. In data corresponding
to 6.0 fb-1 of integrated luminosity, we obtain good agreement with
standard model predictions, and set limits on the chargino-neutralino
production cross section for simplified gravity- and gauge-mediated
models. As an example, assuming that the chargino and neutralino decays
to taus dominate, in the simplified gauge-mediated model we exclude cross
sections greater than 300 fb at 95% credibility level for chargino and
neutralino masses of 225 GeV/c2. This analysis is the first to extend the
LHC searches for electroweak supersymmetric production of gauginos to high
tan beta and slepton next-to-lightest supersymmetric particle scenarios.
