An Isobaric Model for Kaon photoproduction

Abstract

The kaon photoproduction is analyzed up to $E_{\gamma }^{\mathrm{Lab}}$=2.0 GeV by using an isobaric model based on effective Lagrangians and by taking a cross symmetry into account. Both {\it pseudovector} and {\it pseudoscalar} couplings for kaon-baryon-baryon (baryon spin=1/2) interactions are considered with form factors. A vector meson($K^{\ast }(890)$), an axial vector meson($K_1(1270)$), nucleon resonances($J\le 5/2$), and hyperon resonances($J\le 3/2$) are treated as participating particles. By determining unknown coupling constants through a systematic fitting of the differential cross section, the total cross section, the single polarization observable, and the radiative kaon capture branching ratio to their experimental data, we find out a simple model which reproduces all the experimental data well.
