Description
In the experiments at the SPHINX facility on the 70 GeV proton beam of the IHEP accelerator a wide program of studying of the baryon diffractive production and search for exotic baryons in these processes is being carried out. The first data for the reactions p + N → (K+K-p) + N, p + N → (pφ) + N and p + N → [Λ(1520)K+] + N are presented. The very sensitive upper limits for the cross sections for diffractive production of heavy narrow cryptoexotic baryon resonances with hidden strangeness in the mass region up to 4.5 GeV are obtained. 14 refs., 12 figs., 2 tabs
