Description
High-precision data on neutral kaon production collected by the HADES collaboration in proton-niobium collisions at a beam energy of 3.5 GeV were analysed with the aim to extract the kaon in-medium potential. Predictions of the Chiral Perturbation Theory (ChPT) for the kaon in-medium properties were tested by means of GiBUU transport model simulations. The uncertainties of the model were considered in detail. The data support the presence of a repulsive potential that amounts to ≈35 MeV at normal nuclear density for kaons at rest. These results set an important benchmark for future studies of dense nuclear matter by means of strange probes.
