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.
