摘要：
In supersymmetric theories with R-parity breaking, sleptons can be produced in quark-antiquark annihilation at the Tevatron through interactions in which two quark fields are coupled to a slepton field. If at the same time trilinear slepton-lepton-lepton couplings are present, the sleptons can be searched for as resonances in p (p) over bar --> <(nu)over tilde> --> l(+)l(-) and <(tau)over tilde> --> l nu final states. Existing Tevatron data can be exploited to derive bounds on the Yukawa couplings of sleptons to quark and lepton pairs. Similar bounds can also be obtained from e(+) e(-) annihilation to hadrons at LEP2. (C) 1997 Elsevier Science B.V.
