Exotic strange multibaryon states searches with $Λ$- hyperon and $K^0_s$- meson systems in p+A collisions at momentum 10 GeV/c
Abstract
Description
Review for exotic strange multibaryon states were obseved in the effective mass spectra of: 1)$Λπ^+$, $Λπ^-$, $Λp$, $Λp p$, and $ΛK^0_S$, $K^0_Sπ^{\pm}$ and $K^0_Sp$ subsystems.The invariant mass of $Λπ^+$ and $K^0_Sπ^{\pm}$ spectra has observed well known $Σ^{*+}$(1385) and $K^{*\pm}$(892) resonances. The width of $Σ^{*-}(1385)$ for p+A reaction is two time larger than that presented in PDG. The cross section of $Ξ^-\to Λπ^-$ is 7-8 times larger than expected geometrical cross section in p+propane interaction. A few events detected on the photographs of the propane bubble chamber, were interpreted as S=-2 light and heavy $H^{0,+}$ dibaryons.
