Abstract
In the experiments on the SPHINX facility using the 70-GeV proton beam of the IHEP accelerator, a broad program aimed at the study of baryon diffractive production and the search for exotic baryons in these pro cesses is carried out. The first data for the p + N --> (K+K-p) + N, p + N --> (pphi) + N, and p + N --> [LAMBDA(1520)K+] + N reactions are presented. The ultrasensitive upper limits for the cross sections of d iffractive production of heavy narrow cryptoexotic baryon resonances w ith hidden strangeness in the mass region to 4.5 GeV are obtained.
