中微子带电电流类准弹性散射是一种广泛应用于中微子振荡测量的反应类别，它探测了控制中微子-核相互作用的核效应。这封信报告的三重微分截面的$ν_μ$准弹性反应使用烃介质的MINERvA探测器暴露于宽频带光束跨越2 $\leq$ E $_ν\leq$ 20 GeV的第一次测量。测量映射横向和纵向μ介子动量和总质子动能之间的相关性，并将其与最先进的模拟预测进行比较。观察到的不确定性，可能反映短缺与模型的π介子和核子核内散射和/或观众核子喷射从打击核。轻子变量和强子变量的分别确定可以为中微子能量估计的实验方法提供信息。
英文摘要：
Neutrino charged-current quasielastic-like scattering, a reaction category extensively used in neutrino oscillation measurements, probes nuclear effects that govern neutrino-nucleus interactions. This Letter reports the first measurement of the triple-differential cross section for $ν_μ$ quasielastic-like reactions using the hydrocarbon medium of the MINERvA detector exposed to a wide-band beam spanning 2 $\leq$ E$_ν\leq$ 20 GeV. The measurement maps the correlations among transverse and longitudinal muon momenta and summed proton kinetic energies, and compares them to predictions from a state-of-art simulation. Discrepancies are observed that likely reflect shortfalls with modeling of pion and nucleon intranuclear scattering and/or spectator nucleon ejection from struck nuclei. The separate determination of leptonic and hadronic variables can inform experimental approaches to neutrino-energy estimation.
