Two-body hyperon final states in antiproton interactions at 2.2 GeV/c

Summary

The reactions$\bar pp \to \bar \Lambda \Lambda$,$\bar \Lambda \Sigma ^0 + C.C.$,$\bar \Sigma ^ + \Sigma ^ +$ and$\bar \Sigma ^ - \Sigma ^ -$ are studied at 2.2 GeV/c. The cross-section, differential cross-section, polarization and spin correlations (between the$\bar \Lambda$ and Λ hyperons) are discussed.

Riassunto

Si studiano le reazioni$\bar pp \to \bar \Lambda \Lambda$,$\bar \Lambda \Sigma ^0 + c.c.$, Σ⁺Σ⁺ e Σ⁻Σ⁻ e 2.2 GeV/c. Si discutono la sezione d’urto, la sezione d’urto differenziale, la polarizzazione e le correlazioni degli spin (fra gli iperoni$\bar \Lambda$ e Λ).
