论文摘要
我们研究深度非弹性散射中的Lepton-Jet相关性。我们对自旋平均和横向自旋依赖差截面进行一环计算，具体取决于最终态Lepton和JET的总横向动量。横向动量依赖性（TMD）分解形式主义用于描述相关的可观察物。为了显示这一过程的物理范围，我们对HERA运动学进行了现象学研究，并对持续的实验数据分析发表了评论。此外，我们强调了这一过程限制小$ x $动力学的潜力。
We study the lepton-jet correlation in deep inelastic scattering. We perform one-loop calculations for the spin averaged and transverse spin dependent differential cross sections depending on the total transverse momentum of the final state lepton and the jet. The transverse momentum dependent (TMD) factorization formalism is applied to describe the relevant observables. To show the physics reach of this process, we perform a phenomenological study for HERA kinematics and comment on an ongoing analysis of experimental data. In addition, we highlight the potential of this process to constrain small-$x$ dynamics.
