    "abstract": "We calculate the momentum-dependent potentials for $K^+$ and $K^-$ mesons in\na dispersion approach at nuclear density $\\rho_0$ using the information from\nthe vacuum $K^+ N$ and $K^- N$ scattering amplitudes, however, leaving out the\nresonance contributions for the in-medium analysis. Whereas the $K^+$ potential\nis found to be repulsive ($\\approx$ + 30 MeV) and to show only a moderate\nmomentum dependence, the $K^-$ selfenergy at normal nuclear matter density\nturns out to be $\\approx$ - 200 MeV at zero momentum in line with kaon atomic\ndata, however, decreases rapidly in magnitude for higher momenta. The antikaon\nproduction in p + A reactions is calculated within a coupled transport approach\nand compared to the data at KEK including different assumptions for the\nantikaon potentials. Furthermore, detailed predictions are made for $p +\n^{12}C$ and $p + ^{207}Pb$ reactions at 2.5 GeV in order to determine the\nmomentum dependent antikaon potential experimentally.",
