Search for exotic baryon states with the SPHINX detector

A number of diffractive processes involving the production of baryon states are studied in a series of experiments using the SPHINX detector and the E{sub p} = 70 GeV proton beam of the IHEP accelerator. These include p + N {yields} [pK{sup +}K{sup {minus}}] + N, p + N {yields} [p{phi}] + N, p + N {yields} [{Lambda}(1520)K{sup +}] + N, p + N {yields} [{Sigma}(1385){sup 0}K{sup +}] + N, p + N {yields} [{Sigma}(1385){sup 0}K{sup +}] + N + (neutrals), p + N {yields} [{Sigma}{sup 0}K{sup +}] + N, and a number of other transitions. Searches for narrow heavy baryons, which are candidates for cryptoexotic hadron states with hidden strangeness, are reported. The first results on meson production in the deep fragmentation region are presented. 21 refs., 14 figs., 2 tabs.
