New data on the p+N→[Σ0K+]+Np + N \to [\Sigma^0K^+] + N reaction at Ep=70E_p = 70 GeV and the search for exotic baryons

New data for the diffractive reaction $p+N \rightarrow [\Sigma^oK^+]+N$ at $E_p$=70 GeV were obtained with partially upgraded SPHINX setup. The data are in a good agreement with the results of our previous study of this reaction. In the mass spectrum $M(\Sigma^oK^+)$ a structure at the threshold region with a mass ~1810 MeV and a distinct $X(2000)$ peak with $M=1989\pm6$ MeV and $\Gamma=91\pm20$ MeV are observed. Unusual features of the massive $X(2000)$ state (narrow decay width, anomalously large branching ratio for the decay channel with strange particle emission) make it a serious candidate for cryptoexotic pentaquark baryon with hidden strangeness $|qqqs\bar s>$. We also present new results on the narrow threshold structure X(1810) with $M=1807\pm7$ MeV and $\Gamma=62\pm19$ MeV which is produced in the region of very small $P^2_T<$0.01 GeV$^2$. The possibility of the Coulomb production mechanism for X(1810) is discussed
