K Kbar photoproduction and S-P wave interference

Abstract

Results of a new analysis of the $K^{+}{K}^{-}$ photoproduction at two photon energies $E_{\gamma }=4GeV$ 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.
