Kaon and hyperon production in antiproton-induced reactions on nuclei    [PDF]

A. B. Larionov, T. Gaitanos, U. Mosel

We study the strangeness production in antiproton-nucleus collisions at the
beam momenta from 200 MeV/c to 15 GeV/c within the Giessen
Botzmann-Uehling-Uhlenbeck (GiBUU) transport model. The GiBUU model contains a
very detailed description of the underlying antinucleon-nucleon cross sections,
in-particular, of the strangeness production channels. We compare our
calculations with the bubble chamber data on \Lambda- and K^0_S-production in
antiproton-nucleus collisions and with the earlier intranuclear cascade
calculations. The contributions of the various partial channels to the hyperon
production are reported and systematic differences with experiment are
discussed. The possible formation of the bound \Lambda- and
\Lambda\Lambda-nucleus systems is also considered. Finally, the results on the
\Xi-hyperon production are presented in view of the forthcoming experiments
with antiproton beams at FAIR.
