Аннотация
We present the analysis of the inclusive ${K}^{0}$ production in $p+p$ and $p+\mathrm{Nb}$ collisions measured with the HADES detector (GSI Helmholtzzentrum for Heavy-Ion Research, Darmstadt) at a beam kinetic energy of 3.5 GeV. Data are compared to the Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) transport model. The data suggest the presence of a repulsive momentum-dependent kaon potential as predicted by the chiral perturbation theory (ChPT). For the kaon at rest and at normal nuclear density, the ChPT potential amounts to $\ensuremath{\approx}35$ MeV. A detailed tuning of the kaon production cross sections implemented in the model has been carried out to reproduce the experimental data measured in $p+p$ collisions. The uncertainties in the parameters of the model were examined with respect to the sensitivity of the experimental results from $p+\mathrm{Nb}$ collisions to the in-medium kaon potential.
