Abstract

We investigate the exclusive proton-induced $K^{+}$ production near the kaon threshold. Compared are two models: a meson-exchange model, which includes $π$ , ρ $,$ K $an d$ K^\ast $e x c han g e, t o g e t h er w i t h t h e d o minan t ba r y o n r eso nan ces, an d a q u a r k - g l u o nm o d e l, w h er e m o m e n t u m s ha r in g i s p r o v i d e d v ia t h ee x c han g eo f tw o g l u o n s .
