Abstract
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.
