    "abstract": "We investigate the exclusive proton-induced $K^+$ production near the kaon\nthreshold. Compared are two models: a meson-exchange model, which includes\n$\\pi$, \\rho$, $K$ and $K^\\ast$ exchange, together with the dominant baryon\nresonances, and a quark-gluon model, where momentum sharing is provided via the\nexchange of two gluons. Based on covariant bound state wave functions for the\nmeson and the baryons - which we treat as quark-diquark objects - first results\nfor the $pp\\to p\\Lambda K^+$ total cross section are presented for both models.",
