Kaons and Antikaons in Nuclear Matter: AA vs. pA Collisions — •Henry Schade1,2 and Burkhard Kämpfer1,2 — 1Institut für Theoretische Physik, TU Dresden, 01062 Dresden, Germany — 2Forschungszentrum Dresden-Rossendorf, PF 510119, 01314 Dresden, Germany
Kaon- and antikaon production near the threshold is studied within a transport approach of Boltzmann-Uehling-Uhlenbeck type with the aim of a concise understanding of medium modifications. The role of (i) the strangeness-exchange reaction π Y → K− N, (ii) the feeding of φ → K+K− and (iii) different models of K±N potentials with momentum dependence is elaborated. We compare our transport model calculations to experimental phase space distributions of K± in the reactions p+C, p+Au, C+C and Ar+KCl (KaoS and HADES data).
