Limits for the central production of Theta^+ and Xi^{--} pentaquarks in 920 GeV pA collisions

B Collaboration, I. Abt

We have searched for Theta^+(1540) and Xi^{--}(1862) pentaquark candidates in proton-induced reactions on C, Ti and W targets at mid-rapidity and \sqrt{s} = 41.6 GeV. In 2x10^8 ine…
