Abstract

K-p interaction is modeled as one-hadron-exchange potential using relativistic kinematic, which is inspired by the success of the Bonn one-boson-exchange potential model for nucleon-nucleon (NN) interaction. The hadrons being exchanged are a scalar meson σ; vector mesons ω and ρ; hyperons Λ and ς; and a 12+ resonance Λ-(1600). We determine the parameters of the potentials by means of fitting processes to experimental data of K-p differential cross section for kaon laboratory kinetice energy of about 48 MeV to 580 MeV. The differential cross sections are calculated using a three-dimensional (3D) technique without partial-wave expansion. This model gives χ2/N=9.9914 and able to reproduce data quite well above 200 MeV. The contribution of Λ-(1600)-resonance shows to be small compared with the others.
