Inspired by the Bonn NN one-boson-exchange potential, a K+p interaction is modeled as one-hadron-exchange potential using relativistic kinematic. The hadrons being exchanged are scalar-meson-σ; vector-meson ω and ρ; hyperon Λ and Σ; and Σ (1385). The parameters are determined by means of fitting process to experimental data of K+p differential cross section for kaon laboratory kinetic energies of about 20 MeV to 593 MeV. The differential cross sections are calculated using a 3D technique. This model seems to require an additional exchange resonance particle to get better results, the contribution of each exchanged particle will also be discussed."
