The chargino-neutralino production is one of the most promising
SUSY processes that could be observed at the Tevatron. Cross sections of
the order 0.1 pb have not been excluded yet under the mSUGRA scenario,
whereas the trilepton signature of the process is not contaminated by
significant standard model backgrounds. We report on the status of CDF
search for chargino-neutralino production at the Tevatron by presenting the
results of five multilepton subanalyses as well as the result of their
combination which leads to our current lower limit on the chargino mass of
127 GeV/c2 and upper limit on the production cross section times branching
ratio to leptons of 0.25 pb at 95% confidence level.
