Spin Correlations of Λ Hyperons in the SELEX Experiment

Two-particle correlations of the pairs of identical Λ hyperons in Σ− A interactions were studied based on the statistical data obtained in the SELEX experiment performed using the Tevatron collider at FNAL in 1996–1997. The preliminary results from the investigations of spin correlations of ΛΛ pairs are presented, and the dimension of the region of ΛΛ generation is estimated. The results are in good agreement with the world data and the result obtained using correlation function analysis.
