Inclusive cross sections for Ξ- hyperon production in high-energy Σ-, π- and neutron induced interactions were measured by the experiment WA89 at CERN. Secondary Σ- and π- 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 Ξ- 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 xF. A strong leading effect for Σ- produced by Σ- is observed.
