Abstract

We report the first measurement of flux-integrated double-differential quasielasticlike neutrino-argon cross sections, which have been made using the Booster Neutrino Beam and the MicroBooNE detector at Fermi National Accelerator Laboratory. The data are presented as a function of kinematic imbalance variables which are sensitive to nuclear ground-state distributions and hadronic reinteraction processes. We find that the measured cross sections in different phase-space regions are sensitive to different nuclear effects. Therefore, they enable the impact of specific nuclear effects on the neutrino-nucleus interaction to be isolated more completely than was possible using previous single-differential cross section measurements. Our results provide precision data to help test and improve neutrino-nucleus interaction models. They further support ongoing neutrino-oscillation studies by establishing phase-space regions where precise reaction modeling has already been achieved.

摘要

我们报告了首次对通量积分双微分类准弹性中微子 - 氩核截面的测量，该测量是利用费米国家加速器实验室的助推器中微子束和MicroBooNE探测器进行的。数据呈现为运动学不平衡变量的函数，这些变量对核基态分布和强子再相互作用过程敏感。我们发现，在不同相空间区域测量的截面对不同的核效应敏感。因此，与之前使用单微分截面测量相比，它们能更全面地分离特定核效应对中微子 - 核相互作用的影响。我们的结果提供了精确数据，有助于检验和改进中微子 - 核相互作用模型。通过建立已经实现精确反应建模的相空间区域，它们进一步支持了正在进行的中微子振荡研究。
