Abstract
We study the role of magnetic interaction in the photoproduction of the kaon and hyperon. We find that the inclusion of a higher order diagram induced by the Wess-Zumino-Witten term has a significant contribution to the magnetic amplitude, which is compatible to the observed photon asymmetry in the forward angle region. This enables us to use the Kâ coupling constants which have been determined in a microscopic way rather than the phenomenological ones which differ largely from the microscopic ones.
