Production and interaction of neutral kaons in proton-proton and proton-nucleus reactions at 3.5 GeV beam energy — •Kirill Lapidus and Jia-Chii Berger-Chen — Excellence Cluster ’Universe’, Boltzmannstr. 2, 85748, Garching, Germany

Results on the inclusive K⁰-meson production in proton-proton and proton-niobium collisions will be presented. The high-statistics (∼ 10⁴ kaons) data were measured by the HADES experiment (GSI Helmholtzzentrum), employing a proton beam with a kinetic energy of 3.5 GeV. Differential cross sections, reconstructed in p+p collisions, are compared with predictions of a resonance model for kaon production. The GiBUU transport code, which includes the resonance model, is used for the interpretation of the data, obtained in p+⁹³Nb reactions. On the basis of GiBUU simulations, the sensitivity of the measurements to the in-medium kaon-nucleon scattering and the repulsive kaon-nucleus potential will be discussed.
