Strange Multibaryon States with ΛHyperon Systems in pa Collision at 10 Gev/c
Abstract
Description
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 $Λp p$ 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 $H^0$ 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 weak decay channels of $K^-pp$ or $ Σ^+ pπ^-$.
