我们导出了量子色动力学子过程γ g→（J <$）g的振幅，用一个特定的波函数把J <$表示成一个c-c系统.利用这些结果得到了非弹性过程γ N→（J <$）X的归一化总截面σ γ、非弹性J <$光生的z和p-T依赖性的预测以及J <$螺旋度的预测。这些预测也适用于小Q2的电生产.
Amplitudes are derived for the quantum-chromodynamic subprocess γ g→(J ψ) g, with a specific wave function used to represent the J ψ as a c c system. The results are used to obtain the normalized total cross section σ γ for the inelastic process γ N→(J ψ) X, predictions for the z and p T dependence of inelastic J ψ photoproduction, and predictions for the J ψ helicity. The predictions apply as well to electroproduction at small Q 2.
