title = "Pseudoscalar and scalar meson photoproduction interpreted by Regge phenomenology",
abstract = "We have evaluated pseudoscalar and scalar neutral pion photoproduction in γ - p→π0p and a00p above the resonance region and within Regge phenomenology. Our fit, including GlueX ς pseudoscalar photoproduction data, shows that previous Stanford Linear Accelerator Center (SLAC) ς measurements for γ - p→π0p above Eγ=4GeV vary substantially from SLAC data with more recent measurements made by GlueX in the vicinity of Eγ=9GeV. The Regge model predicts that the beam polarization asymmetry ς of the scalar meson is opposite to that of pseudoscalar meson photoproduction; however, the cross sections are similar. While the natural parity vector meson exchange is dominant in both cases, the contribution of the unnatural parity pseudovector meson exchange is very small. Using Regge phenomenology, we predicted high-energy behavior for double polarized observables E, F, G, and H for the reactions γp→π0p and a00p.",
