论文摘要

我们介绍了差异横截面的第一个测量,用于与一个哑光,两个质子和最终状态中无酸的氩气中微子相互作用。这些最终状态以两种核子的敲除相互作用为主,这些相互作用对于模型来说是复杂的,目前对这些相互作用在现有中微子 - 核散射数据中的特征的信息有限。对两核子敲除的详细研究对于支持探索中微子性质的即将进行的实验至关重要。在测得的不同运动量中,两个质子之间的开头,总质子动量和哑光之间的角度以及最终状态系统的总横向动量对各种理论模型所体现的基础物理过程最敏感。

We present the first measurement of differential cross sections for charged-current muon neutrino interactions on argon with one muon, two protons, and no pions in the final state. These final states are dominated by two-nucleon knockout interactions, which are complicated to model and for which there is currently limited information about the characteristics of these interactions in existing neutrino-nucleus scattering data. Detailed investigations of two-nucleon knockout are vital to support upcoming experiments exploring the nature of the neutrino. Among the different kinematic quantities measured, the opening angle between the two protons, the angle between the total proton momentum and the muon, and the total transverse momentum of the final state system are most sensitive to the underlying physics processes as embodied in various theoretical models.
