    "abstract": "A dynamical model for S-- and P--wave correlated $2 \\pi$ (and $K \\bar K$)\nexchange between a kaon and a nucleon is presented, starting from corresponding\n$N \\bar N \\rightarrow K \\bar K$ amplitudes in the pseudophysical region, which\nhave been constructed from nucleon, $\\Delta$--isobar and hyperon ($\\Lambda$,\n$\\Sigma$) exchange Born terms and a realistic meson exchange model of the $\\pi\n\\pi \\rightarrow K \\bar K$ and $K \\bar K \\rightarrow K \\bar K$ amplitude. The\ncontribution in the s--channel is then obtained by performing a dispersion\nrelation over the unitarity cut. In the $\\rho$--channel, considerable\nambiguities exist, depending on how the dispersion integral is performed. Our\nmodel, supplemented by short range interaction terms, is able to describe\nempirical $K^+ N$ data below pion production threshold in a satisfactory way.",
