Abstract：
Based on the Ingelman-Schlein model for hard diffractive scattering and the factorization formalism of non-relativistic QCD for quarkonia production, we present a study of associated J/ψ+γ production through single Pomeron exchange approaching Tevertron energy region. It is found that the p_T distribution of the cross section is sensitive to the color octet matrix elements. But the ratios of the inclusive production cross section to the single diffractive production cross section are not so. The ratios are sensitive to the product Df_g. The experimental mesurement of this process at the Tevetron would shed light on the nature of the Pomeron and test the diffractive hard scattering factorization.
