An investigation of the {anti p}p {yields} {anti {Lambda}} {Lambda} and {anti p}p {yields} {anti {Sigma}}{sup 0} {Lambda} + c.c. reactions near threshold

Description

Experiment PS 185 studies the production of antihyperon-hyperon pairs in antiproton-proton collisions at LEAR in the near-threshold energy region. The {ital {anti p} p} {r_arrow} {anti {Lambda}}{Lambda} reaction has been thoroughly studied by PS185 and many high-quality data have been reported. New results, including total and differential cross sections along with spin observables, are presented here for the channels {ital {anti p} p} {r_arrow} {anti {Lambda}}{Lambda} and {ital {anti p}p} {r_arrow} {anti {Sigma}}{sup 0}{Lambda} + c.c at incident lab antiproton momenta of 1.726 and 1. 771 GeV/c. The data from the relatively unstudied and complementary {ital {anti p}p} {r_arrow} {anti ... continued below

The data from the relatively unstudied and complementary {ital {anti p}p} {r_arrow} {anti {Sigma}}{sup 0}{Lambda} + c.c channel is compared to that from {ital {anti p}p} {r_arrow} {anti {Lambda}}{Lambda} at similar energies above the reaction threshold.
