Query: Chargino Pair Production at LEP2 with Broken R-Parity: 4-jet Final
  States   We study the pair production of charginos in e+e- collisions followed by the
decay via R-parity violating LQD operators. We determine the complete matrix
element squared for chargino decays via LQD or LLE operators. We find regions
in MSSM parameter space where the chargino mass is 52.5GeV and the R-parity
violating decays of the charginos dominate the gauge decays to neutralinos. At
LEP2 this then leads to additional 4 jet events which could explain the excess
recently observed by ALEPH.
