| Abstract: | The reactions of baryon diffractive productionp+N→(pK + K ?)+N, p+N→(p?)+N, p+N→Λ(1520)K +]+N p+N→Σ(1385) o K +]+N in the 70 GeV proton beam were studied. Very sensitive upper limits for the production cross sections of heavy narrow cryptoexotic baryon resonances with hidden strangeness were obtained. |
