R-Parity Violating Signals at Existing Colliders
  Formation of the $s$-channel slepton resonances at LEP2 or Tevatron at current energies is an exciting possibility in R-parity violating SUSY models. Existing LEP2 and Tevatron data can be exploited to look for sleptons, or to derive bounds on the Yukawa couplings of sleptons to quark and lepton pairs.
