Parameterization of Form Factors of a K-p Interaction Model Based on One Hadron Exchange

摘要

K-p interaction is modeled as one hadron exchange potential with the exchanged hadrons being scalar-meson-σ; vector-meson-ω, p; and hyperon-A, Σ. The cutoff parameters of the form factors at each vertex are determined by means of fitting processes to experimental data of K-p differential cross section for scattering laboratory energies of about 50 MeV to 225 MeV. The differential cross sections are calculated using a three-dimensional technique without partial-wave expansion. We obtain a K-p interaction model with χ~2/N value being 3.9.
