In a generic supersymmetric extension of the standard model, there will be
lepton flavor violation at a neutral gaugino vertex due to misalignment bet
ween the lepton Yukawa couplings and the slepton soft masses. Sleptons prod
uced at the CERN LHC through the cascade decays of squarks and gluinos can
give a sizable number of events with 4 leptons. This channel could give a c
lean signature of supersymmetric lepton flavor violation under conditions w
hich are identified.
