Ξ− production in antiproton–nucleus collisions at 3 GeV/c

We analyse in detail a recently proposed technique for producing high rates of Ξ− hyperons from beams and for their slowing down until rest, as planned for the Double-Hypernuclei experiment at the future HESR-GSI facility. We describe the Monte Carlo event generator that we developed for this purpose, and discuss the numerical results obtained within our model, in connection with the expected performances and operation modes of the HESR ring.
