The kaon photoproduction up to E γLab= 2.0 GeV is analyzed by an isobaric model based
on effective Lagrangians. Both pseudovector and pseudoscalar coupling schemes for kaon–
baryon–baryon (baryon spin= 1/2) interactions are considered with form factors. A vector
meson (K∗(890)), an axial-vector meson (K 1 (1270)), nucleon resonances (J⩽ 5/2), and
hyperon resonances (J⩽ 3/2) are treated as participating particles. Coupling constants
relevant to the particle, most of which are still unknown, are determined through a systematic …
