$\Xi ^{-}$ Production by $\Sigma ^{-}$,$\pi^{-}$ and Neutrons in the Hyperon Beam Experiment at CERN

Inclusive cross sections for \ximin\ hyperon production in high-energy \sigmamin, \pimin\ and neutron induced interactions were measured by the experiment WA89 at CERN. Secondary \sigmamin\ and \pimin\ beams with average momenta of 345~\gevc1 and a neutron beam of average momentum 65~\gevc1 were pro...

Descripción
Sumario:Inclusive cross sections for \ximin\ hyperon production in high-energy \sigmamin, \pimin\ and neutron induced interactions were measured by the experiment WA89 at CERN. Secondary \sigmamin\ and \pimin\ beams with average momenta of 345~\gevc1 and a neutron beam of average momentum 65~\gevc1 were produced by primary protons of 450~\gevc1\ 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 \ximin\ produced by \sigmamin\ is observed. The influence of the target mass on the \ximin\ cross section is explored by comparing reactions on copper and carbon nuclei.
