本文报告了中微子相互作用的单产生通道中横向运动不平衡的首次 T2K 测量。我们在 T2K 实验探测器附近的 ND280 离轴处测量了最终状态下碳氢化合物与单个和至少一个质子的 μ 中微子带电电流相互作用的微分截面。将提取的横截面与不同中微子-核相互作用事件生成器的预测进行比较。总体而言，结果表明更倾向于对核介质效应（包括初始核态和最终态相互作用）进行更现实处理的模型。
This paper reports the first T2K measurement of the transverse kinematic imbalance in the single-production channel of neutrino interactions. We measure the differential cross sections in the muon-neutrino charged-current interaction on hydrocarbon with a singleand at least one proton in the final state, at the ND280 off axis near detector of the T2K experiment. The extracted cross sections are compared to the predictions from different neutrino-nucleus interaction event generators. Overall, the results show a preference for models that have a more realistic treatment of nuclear medium effects including the initial nuclear state and final-state interactions.
