Abstract: 
We study the strangeness production in antiproton-nucleus collisions at beam momenta from 200 MeV/c to 15 GeV/c and in (p) over bar annihilation at rest within the Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) transport model. The GiBUU model contains a very detailed description of underlying antinucleon-nucleon cross sections, in particular, of the strangeness production channels. We compare our calculations with experimental data on Lambda, K-S(0), and (Lambda) over bar production in (p) over bar A collisions and with earlier intranuclear cascade calculations. The contributions of various partial channels to the hyperon production are reported and systematic differences with the experiment are discussed. The possible formation of bound Lambda- and Lambda Lambda-nucleus systems is also considered. Finally, results on the Xi hyperon production are presented in view of forthcoming experiments with antiproton beams at the Facility for Antiproton and Ion Research.
