    "abstract": "The production of $K^+$ mesons in proton-nucleus collisions from 1.0 to 2.3\nGeV is analyzed with respect to one-step nucleon-nucleon $(NN\\to N Y K^+$) and\ntwo-step $\\Delta$-nucleon $(\\Delta N \\to K^+ Y N$) or pion-nucleon $(\\pi N \\to\nK^+ Y $) production channels on the basis of a coupled-channel transport\napproach (CBUU) including the kaon final-state-interactions (FSI).\nMomentum-dependent potentials for the nucleon, hyperon and kaon in the final\nstate are included as well as $K^+$ elastic rescattering in the target nucleus.\nThe transport calculations are compared to the experimental $K^+$ spectra taken\nat COSY-J\\\"ulich. Our systematic analysis of $K^+$ spectra from $^{12}C$,\n$^{63}Cu$, $^{107}Ag$ and $^{197}Au$ targets as well as their momentum\ndifferential ratios gives a repulsive $K^+$ potential of $20\\pm 5 $ MeV at\nnormal nuclear matter density.",
