Abstract

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+\Lambda \pi^+(Σ+\Sigma^{*+}(1382),PDG), Λp\Lambda p and Λpp\Lambda p p 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 H0H^0 light(<M(ΛΛ)<M_{(\Lambda \Lambda)}) and heavy H0,+H^{0,+}. New event, detected on the photographs of the propane bubble chamber was interpreted as heavy H+(2488)H^+(2488) dibaryon by weak decay channels of KppK^-pp or Σ+pπ \Sigma^+ p\pi^-.
