Strange multibaryon states with Λ hyperon systems in pA collision at 10 GeV/ c

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 = −2H 0 light(propane bubble chamber was interpreted as heavy H + (2488) dibaryon by weak decay channels of K − pp or Σ+ pπ−.
