Search for exotic baryons in 800-GeV pp ---> p Xi+- pi+- X

We report the results of a high-statistics, sensitive search for narrow baryon resonances decaying to {xi}{sup -}{pi}{sup -}, {xi}{sup -}{pi}{sup +}, {xi}{sup +}{pi}{sup -}, and {xi}{sup +}{pi}{sup +}. The only resonances observed are the well known {xi}{sup 0}(1530) and {xi}{sup 0}(1530). No evidence is found for the states near 1862 MeV, previously reported by NA49 [Phys. Rev. Lett. 92, 042003 (2003)]. At the 95% confidence level, we find the upper limit for the production of a Gaussian enhancement with {sigma}=7.6 MeV in the {xi}{sup -}{pi}{sup -} effective mass spectrum to be 0.3% of the number of observed {xi}{sup 0}(1530){yields}{xi}{sup -}{pi}{sup +}. We find similarly restrictive upper limits for an enhancement at 1862 MeV in the {xi}{sup -}{pi}{sup +}, {xi}{sup +}{pi}{sup -}, and {xi}{sup +}{pi}{sup +} mass spectra.We report the results of a high-statistics, sensitive search for narrow baryon resonances decaying to
