我们报告的第一次测量通量积分双微分准弹性类中微子氩截面，这已经取得了使用助推器中微子束和MicroBooNE探测器在费米国家加速器实验室。这些数据是作为一个函数的运动学不平衡变量，这是敏感的核基态分布和强子再相互作用过程。我们发现，在不同的相空间区域的测量截面是不同的核效应敏感。因此，它们使特定核效应对中微子-核相互作用的影响能够比使用以前的单微分截面测量更完全地隔离。我们的结果提供了精确的数据，以帮助测试和改进中微子-核相互作用模型。他们通过建立已经实现精确反应建模的相空间区域，进一步支持正在进行的中微子振荡研究。
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.
