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