Abstract
Results of a new analysis of the K+K- photoproduction at two photon energies Eγ= 4GeV and 5.65GeV with a particular emphasis on the S-wave production are presented. We show that the proper treatment of all the helicity components of the S- and P-waves enables one to eliminate the reported discrepancies in extraction of the S-wave photoproduction cross section from experimental data.
