Abstract

We present the transverse momentum spectra and rapidity distributions of π^- and K_S⁰ in Ar + KCl reactions at a beam kinetic energy of 1.756 A GeV measured with the High Acceptance Di-Electron Spectrometer (HADES). The reconstructed K_S⁰ sample is characterized by good event statistics for a wide range in momentum and rapidity. We compare the experimental π^- and K_S⁰ distributions to predictions by the Isospin Quantum Molecular Dynamics (IQMD) model. The model calculations show that K_S⁰ at low transverse momenta constitute a particularly well-suited tool to investigate the kaon in-medium potential. Our K_S⁰ data suggest a strong repulsive in-medium K⁰ potential of about 40 MeV strength.

N2 - We present the transverse momentum spectra and rapidity distributions of π- and KS0 in Ar + KCl reactions at a beam kinetic energy of 1.756 A GeV measured with the High Acceptance Di-Electron Spectrometer (HADES). The reconstructed KS0 sample is characterized by good event statistics for a wide range in momentum and rapidity. We compare the experimental π- and KS0 distributions to predictions by the Isospin Quantum Molecular Dynamics (IQMD) model. The model calculations show that KS0 at low transverse momenta constitute a particularly well-suited tool to investigate the kaon in-medium potential. Our KS0 data suggest a strong repulsive in-medium K0 potential of about 40 MeV strength.
