    "abstract": "We study the antikaon potential at finite momentum for proton and neutron\nnuclear matter. Our approach is based on the momentum dependence of the real\npart of the total $K^-N$ scattering amplitude, which is fixed in free space by\nexperimental data, using the dispersion relation approach. We decompose the\ncontributions to the scattering amplitude from different processes and consider\nthe $\\Lambda$(1405) and $\\Sigma$(1385) to be dissolved in nuclear matter at\ndensity $\\rho_0$. Within this approach the $K^-$ potential is found to be\nattractive up to high kaon momenta. Our result is in line with the data on the\nantikaon potential evaluated from the analysis of kaonic atoms (low momenta),\nheavy-ion (interdmediate momenta) and proton-nucleus (high momenta) collisions.",
