摘要
我们计算了在高能 onium-onium 散射中包含 pomeron 环效应的包 Inclusive 单胶子生产横截面。 resulting inclusive cross section given by k_T-factorization formula with one of the unintegrated gluon distribution functions depending on the total onium-onium scattering cross section, which includes all pomeron loops and has to be found independently. 我们讨论了结果适用范围，并认为其由 pomeron 环求和方法的适用范围决定。由于得到的 k_T-factorization 公式具有红外发散，我们得出结论，要 consistently 计算 (红外-有限) onium-onium 散射中胶子生产横截面，必须包含超出 pomeron 环近似的修正项。
