The Observed Correlations for the Strange Multibaryon States in Systems with $\Lambda$-Hyperon from pa Collision at Momentum of 10 Gev/$c$

Abstract

he observed well-known resonances ${\Sigma }^0$ ${\Sigma }^{\ast +}$(1385) and $K^{\ast \pm }$(892) from PDG are good tests of this method. Exotic strange multibaryon states have been observed in the effective mass spectra of: $\Lambda {\pi }^{\pm }$,$\Lambda \gamma$, $\Lambda p$, $\Lambda pp$ subsystems. The mean value of mass for ${\Sigma }^{\ast -}(1385)$ resonance is shifted till mass of 1370 MeV/$c^2$ and width is two times larger than the same value from PDG. Such kind of behavior for width and invariant mass of ${\Sigma }^{\ast -}(1385)$ resonance is interpreted as extensive contribution from stopped ${\Xi }^{-}\to \Lambda {\pi }^{-}$ and medium effect with invariant mass. The mean value of mass for ${\Sigma }^{\ast +}(1385)$ from secondary interactions is also shifted till mass of 1370 MeV/$c^2$. The width of ${\Sigma }^0$ is $\approx$ 2 times larger than the experimental error. There are enhancement production for all observed hyperons.
