| dc.description | Strange multi-baryonic clusters are an exiting possibility to explore the properties of cold dense baryonic matter. Recent results on searches for exotic narrow resonances with $Λ$ hyperon subsystems are reviewed. The observation of $Σ^0$, $Σ^{*+}$(1385) and $K^{*\pm}$(892) well known resonances from PDG are a good tests of this method. The mean value of mass for $Σ^{*-}(1385)$ resonance is shifted till mass of 1370 MeV/$c^2$ and width is two times larger than same value from PDG. Such of behavior for width and mass of $Σ^{*-}(1385)$ resonance interpreted as extensive contribution from stopping $Ξ^-\toΛπ^-$ and medium effect with mass of $Σ^{*-}(1385)$ resonance.In ($Λπ^+ π^-$) spectrum there are observed enhancement signals from $Λ^*(1600)$, $Λ^*(1750)$ and $Λ^*(1850)$ resonances. A number of significant signals were found in the effective mass spectra of: 1)$Λγ$,$p γ$ $Λπ^{\pm}$,$Λππ$, $Λp$ and $Λp p$ subsystems. | |
