Abstract

Inspired by the success of the Bonn NN one-boson-exchange potential model, we tried to model a K+p interaction as one-hadron-exchange potential using relativistic kinematic. The hadrons being exchanged are a scalar- meson-σ; vector-mesons ω and ρ; hyperons Λ and ς; and a spin 3/2 resonance ς∗ (1385). The parameters are determined by fitting process to data of K+p differential cross section experiment for kaon laboratory kinetic energies of about 20 MeV to 600 MeV. The calculation of the differential cross sections are using a 3D technique, which does not use partial wave expansion. We get a χ2/N of 29.4, thus, the model seems to require additional exchanges of resonances to get better results. The contributions of each exchanged particles are also discussed.
