Abstract: 

Antiproton annihilations on nuclei provide a very interesting way to study the behaviour of strange particles in the nuclear medium. In low energy annihilations, the hyperons are produced mostly by strangeness exchange mechanisms. Thus, hyperon production in interactions is very sensitive to the properties of the antikaon-nucleon interaction in nuclear medium. Within the Giessen Boltzmann–Uehling–Uhlenbeck transport model (GiBUU), we analyse the experimental data on Λ and production in collisions at p _lab = 0.2 − 4 GeV/c. A satisfactory overall agreement is reached, except for the production in Ne collisions at p _lab = 608 MeV/c, where we obtain substantially larger production rate. We also study the Ξ hyperon production, important in view of the forthcoming experiments at FAIR and J-PARC.
