Abstract
We present the transverse momentum spectra and rapidity distributions of and K in Ar+KCl reactions at a beam kinetic energy of 1.756 A GeV measured with the spectrometer HADES. The reconstructed K sample is characterized by good event statistics for a wide range in momentum and rapidity. We compare the experimental and K distributions to predictions by the IQMD model. The model calculations show that K at low tranverse momenta constitute a particularly well suited tool to investigate the kaon in-medium potential. Our K data suggest a strong repulsive in-medium K potential of about 40 MeV strength.
