摘要Based on the generalized vector meson dominance model in QCD, we study the photoproduction of vector meson Gamma off the proton by use of the QCD-inspired model in which the contributions from quark-quark, gluon-gluon and quark-gluon interference term to observable are taken into consideration. Calculations are performed for total cross section sigma(tot), differential cross section d sigma/dt, ratio of the real part to imaginary part of forward scattering amplitude rho and nuclear slop parameter function beta. We analyze the individual contributions from quark gluon degrees of freedom and the QCD Odderon to the total cross section sigma(tot) (s), differential cross section d sigma/dt, ratio of the real part to imaginary part of the forward scattering amplitude rho, and nuclear slop parameter function beta. The mediators of interactions between projectiles (the quark and antiquark pair fluctuated from the real photon) and the proton target (three quark system) are the tensor Glueball and Odderon instead of using the usual Pomeron exchange. The theoretical predictions for sigma(tot)(s) are consistent with the experimental data within error bars of the data. The data for d sigma/dt, beta and rho are urgently needed. The gluon-gluon interaction makes a significant contribution to the observables while the Odderon contribution is negligibly small. Therefore, we may conclude that it is impossible to find the QCD Odderon in the gamma + p -> Gamma + p process as suggested before.
