#XI#"- production by #SIGMA#"-, #pi#"- and neutrons in the hyperon beam experiment at CERN

Abstract

Inclusive cross sections for #XI#"- hyperon production in high-energy #SIGMA#"-, #pi#"- and neutron induced interactions were measured by the experiment WA89 at CERN. Secondary #SIGMA#"- and #pi#"- beams with average momenta of 345 GeV/c and a neutron beam of average momentum 65 GeV/c were produced by primary protons of 450 GeV/c from the CERN SPS. Both single and double differential cross sections are presented as a function of the transverse momentum and the Feynman variable x_F. A strong leading effect for #XI#"-produced by #SIGMA#"- is observed. The influence of the target mass on the #XI#"- cross section is explored by comparing reactions on copper and carbon nuclei.
