We present a set of new generalized kinematic imbalance variables that can be measured in neutrino scattering. These variables extend previous measurements of kinematic imbalance on the transverse plane and are more sensitive to modeling of nuclear effects. We demonstrate the enhanced power of these variables using simulation and then use the MicroBooNE detector to measure them for the first time. We report flux-integrated single- and double-differential measurements of charged-current muon neutrino scattering on argon using a topology with one muon and one proton in the final state as a function of these novel kinematic imbalance variables. These measurements allow us to demonstrate that the treatment of charged current quasielastic interactions in genie version 2 is inadequate to describe data. Further, they reveal tensions with more modern generator predictions particularly in regions of phase space where final state interactions are important.

使用 MicroBooNE 探测器的广义运动不平衡变量测量中微子-氩相互作用中的核效应

我们提出了一组新的广义运动不平衡变量，可以在中微子散射中测量。这些变量扩展了先前对横向平面上运动不平衡的测量，并且对核效应的建模更加敏感。我们通过仿真展示了这些变量的增强能力，然后首次使用 MicroBooNE 探测器来测量它们。我们报告了氩气上带电μ子中微子散射的通量积分单和双微分测量，使用最终状态下一个μ子和一个质子的拓扑作为这些新颖的运动不平衡变量的函数。这些测量结果使我们能够证明，精灵版本 2中对带电电流准弹性相互作用的处理不足以描述数据。此外，它们揭示了与更现代的发电机预测的紧张关系，特别是在最终状态相互作用很重要的相空间区域。
