| dc.description | We report on a high-statistics search for the \t1540 resonance in $Σ^-$-nucleus collisions at 340 \gevc1 . No evidence for this resonance was found in our data sample which contains 13 millions $K^0_s \to π^+π^- $ decays above background. For the decay channel $Θ^+ \to K^0_s p$ and the kinematic range $x_F>$ 0.05 we find the production cross section to be $BR(Θ^+ \to K^0_s p)\cdot σ_0 <$ 1.8 $μ$b per nucleon at 99% CL. | |
