Abstract / Description:We report on a high statistics search for the Xi––(1860) resonance in Sigma–-nucleus collisions at 340 GeV/c. No evidence for this resonance is found in our data sample which contains 676000 Xi– candidates above background. For the decay channel Xi––(1860)-->Xi–pi– and the kinematic range 0.15<xF<0.9 we find a 3sigma upper limit for the production cross section of 3.1 and 3.5 µb per nucleon for reactions with carbon and copper, respectively.
