Abstract / Description:We report on a high-statistics search for the Theta(1540)+ resonance in Sigma--nucleus collisions at 340 GeV/c. No evidence for this resonance was found in our data sample which contains 13 million Ks0-->pi+pi- decays above background. For the decay channel Theta+-->Ks0p and the kinematic range xF> 0.05, we find the production cross section to be BR(Theta+-->Ks0p)sigma0<1.8 µb per nucleon at 99% C.L.
