- Аннотация: The inclusive reaction pA -> pK0s+X was studied at IHEP accelerator with 70 GeV/c proton beam using SVD-2 detector. Two different samples of K0s, statistically independent and belonging to different phase space regions were used in the analyses and a narrow baryon resonance with the mass M=1523+-2(stat.)+-3(syst.) MeV/c2 was observed in both samples of the data. The statistical significance was estimated to be of 8.0 sigma (392 signal over 1990 background events). Using the part of events reconstructed with better accuracy the width of resonance was estimated to be Gamma < 14 MeV/c2 at 95 C.L.
