The Impact

The impact of the kaon polarization in nuclear matter on the K− yield in intermediate-energy heavy-ion collisions is investigated. Our scenario of the strange particle production and dynamics is based on an expanding fireball model. This allows for a proper account of in-medium effects. A relation between observed K+ and K− yields is derived. Differential K− cross-sections are calculated and compared with available experimental data taken at various collision energies. It turns out that in-medium effects can modify the K− yields by factors 2 to 5 at beam energies between 2 and 1 AGeV.

Non Equilibrium

A general approach to the kinetics of a hadronic many-particle system is formulated employing a nonequilibrium diagram technique. The investigation of medium effects is based on the analysis of the coupled set of nonequilibrium Dyson equations for the π, N, and Δ components. Some model approaches to their solution are considered. The results are applied to the study of expanding hadronic fireballs containing pions, nucleons, and deltas as produced in the course of heavy-ion collisions at energies provided by the GSI-SIS up to the CERN-SpS.
