Interference Correlations of Hyperons in Neutron-Carbon Interactions

Abstract

The interference correlations of \Lambda-hyperon pairs produced on the carbon target by 20-70 GeV neutrons have been investigated with the EXCHARM spectrometer. Destructive correlations at low relative 4-momenta are observed for \Lambda\Lambda-pairs. No correlations of this type are observed for \Lambda\bar{\Lambda}. Comparison with the corresponding data on meson correlations shows a decrease of production area sizes with an increase of particle masses
