Hypernucleus formation in high-energy nuclear collisions — •Theodoros Gaitanos, Horst Lenske, and Ulrich Mosel — Institut für Theoretische Physik, Universität Giessen, Germany

Hypernucleus production in high energy collisions with rare isotope and antiproton beams will be one of the major projects under study in the new experimental facilities at GSI (HypHI and PANDA collaborations, respectively). Such investigations will be important in understanding the interaction between hyperons and nucleons, which can be accessed so far mainly from studies on hypernuclei. We thus plan to theoretically investigate hypernucleus formation in such dynamical processes (heavy ion and antiproton-nucleus induced reactions at energies above the strangeness production threshold, E_beam∼ 2−5 AGeV, as proposed for the pilot experiment) within kinetic equations of a Boltzmann-type. In particular, since the mechanism of hypernucleus production is not well known in such dynamical situations, we will attempt to study the influence of the cluster coalescence mechanism, secondary pionic rescattering, e.g. π N —→ YK and mean-field applied, on the hypernucleus formation.
