论文摘要
我们以偶然的精度计算以低$ x $的偶极形式中的深度非弹性散射中的二重产量。我们计算纵向或横向极化的单光子交换引起的贡献。我们在GLUON背景字段中包括所有类型的校正，以进行艾科纳尔近似值：（i）目标的有限纵宽宽度，（ii）夸克 - 易药公园与背景字段的subleading（transserve）组件和（iii）$ z^ - $ - $ - $ - 辅助依赖性的目标动态的相互作用。 Dijet横截面的最终表达式写为“广义的Eikonal”贡献的总和（允许纵向动量$ p^+$交换，因为保留了平均$ z^ - $ z^ - $ z^ - $ z^ - $ z^ - 背景字段的依赖性），并且涉及涉及装饰的dipole和quadrupe的近代校正的$ z^ - $。
We compute dijet production in Deep Inelastic Scattering at low $x$ in the dipole formalism at next-to-eikonal accuracy. We calculate the contributions induced by single photon exchange of either longitudinal or transverse polarization. We include all types of corrections to the eikonal approximation in the gluon background field: (i) finite longitudinal width of the target, (ii) interaction of the quark-antiquark pair with the subleading (transverse) component of the background field and (iii) dynamics of the target which is encoded in the $z^-$-coordinate dependence of the background field. The final expressions for the dijet cross section are written as sum of a "generalized eikonal" contribution (where longitudinal momentum $p^+$ exchange between the target and the incoming quark-antiquark pair is allowed since the average $z^-$ dependence of the background field is kept) and explicit next-to-eikonal corrections that involve decorated dipole and quadrupole operators.
