摘要：

We present the results of a search for pair production of scalar top quarks ((t) over tilde (1)) in an R-parity violating supersymmetry scenario in 106 pb(-1) of p (p) over bar collisions at roots=1.8 TeV collected by the Collider Detector at Fermilab. In this mode each (t) over tilde (1) decays into a tau lepton and a b quark. We search for events with two tau's, one decaying leptonically (e or mu) and one decaying hadronically, and two jets. No candidate events pass our final selection criteria. We set a 95% confidence level lower limit on the (t) over tilde (1) mass at 122 GeV/c(2) for Br((t) over tilde (1)-->taub)=1.
