Coupled Channel Analysis of S-Wave Pion-Pion and Kaon-Kaon Photoproduction
arXiv:hep-ph/9710510 · doi:10.1103/PhysRevC.58.1205
Abstract
We present a coupled channel partial wave analysis of nondiffractive S-wave pi+ pi- and K+ K- photoproduction focusing on the KK threshold. Final state interactions are included. We calculate total cross sections, angular and effective mass distributions in both pion-pion and kaon-antikaon channels. Our results indicate that these processes are experimentally measurable and valuable information on the f0(980) resonance structure can be obtained.
