Xi(-) production by Sigma(-), pi(-) and neutrons in the hyperon beam experiment at CERN

Inclusive cross sections for E-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 260 GeV/c were produced by primary protons of 450 GeV/c from the CERN SPS. The influence of the target mass on the Xi(-) cross section is explored by comparing reactions on copper and carbon nuclei. 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 produced by Sigma(-) is observed.
