Description
Kaon interaction with baryonic matter is characterized by a repulsive potential according to common belief.
However, the values of the measured potential are not yet consistent with each other.
We analyze the kaon in-medium behavior employing $K^{0}_{S}$'s identified with the HADES detector in p+p and p+Nb collisions at 3.5 GeV kinetic beam energy. The comparison of the $K^{0}_{S}$ differential cross sections in p+Nb and p+p collisions provides access to the in-medium kaon potential at normal nuclear matter density. The distinctive feature of our measurements is a high-statistics sample of kaons with low transverse momenta ($p_{t} < 100$ MeV$/c$), ensuring the sensitivity to the nuclear matter effects. We present the data analysis method and first results.
