${K{\overline K}}$ photoproduction and S-P-wave interference

Abstract.Results of a new analysis of the K + K- photoproduction at two photon energies, $E_\gamma = 4 \mbox{GeV}$ and $5.65 \mbox{GeV}$, 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 the extraction of the S-wave photoproduction cross section from the experimental data.
