Abstract
The p + N --> [SIGMA0K+] + N reaction was studied in experiments using the SPHINX detector placed in the 70-GeV proton beam of the IHEP acce lerator. In the effective mass spectrum of the M(SIGMA0K+) system prod uced in the coherent diffractive transition, a clear peak with mass M = 1999 +/- 7 MeV and width GAMMA = 91 +/- 17 MeV was observed in addit ion to the near-threshold structure with mass M congruent-to 1800 MeV.
