摘要:

The production of antihyperon‐hyperon pairs out of the antiproton‐proton collison has been studied by the PS185 collaboration using the Low Energy Antiproton Ring (LEAR) at CERN. The emphasis of the studies is to investigate the production threshold region. Results obtained for the reactions p¯p→&Lgr;¯&Lgr; and p¯p→&Lgr;¯&Sgr;°=c.c. are presented and discussed. Total‐ and differential cross sections were measured, polarizations, spin correlations and singlet fractions were extracted at a variety of incident antiproton momenta.The investigations of the collaboration concentrated on the &Lgr;¯&Lgr;‐final channel. Data on p¯p→&Lgr;¯&Lgr; are a vailable for a rather wide energy range. A few results on the &Lgr;&Sgr; channel were analyzed as well as some events for the p¯p→&Sgr;¯+&Sgr;+reaction. Further investigations on the charged sigma final hyperon‐antihyperon pairs are planned and in progress.
