“…Figure 2b shows the invariant mass of 1012(ΛK 0 s ) combinations with bin sizes 18 MeV/c 2 [2]. The solid curve is the sum of the background (detained by the first method) and 2 Breit-Wigner curves(Figure 2b).…”

The review on the 2m propane bubble chamber experiment data analysis aimed to searches for an exotic baryon states for K 0 s -meson subsystems. The observation of Σ 0 , Σ * + (1385) and K * ± (892) well known resonances from PDG are a good tests of this method. There are found a resonant structures for K 0 s π ± , K 0 s p and K 0 s Λ invariant mass spectra which were interpreted as κ(720)-meson, Θ + (1540)-baryon and N 0 (1750) or Ξ 0 -baryon states, respectively.

Experimental data from the 2m propane bubble chamber have been analyzed for exotic baryon states search. A number of peculiarities were found in the effective mass spectra of: Λπ + (Σ * + (1382),PDG), Λp and Λpp subsystems. A few events detected on the photographs of the propane bubble chamber exposed to a 10 GeV/c proton beam, were interpreted as S=-2 H 0 light(< M (ΛΛ) ) and heavy H 0,+ . New event, detected on the photographs of the propane bubble chamber was interpreted as heavy H + (2488) dibaryon by two weak decay channels of K − pp or Σ + pπ − .
