我们提出了双微分测量的反中微子带电电流准弹性散射的MINERvA探测器。这项研究改进了以前的单差测量，通过使用更新的重建算法和相互作用模型，并提供了一个完整的描述所观察到的μ子运动学的形式的双微分横截面相对于μ子的横向和纵向动量。我们包括在我们的信号定义零介子的最终状态所产生的多核子相互作用和共振π介子生产其次是π介子吸收在主核。我们发现，模型的一致性大大提高了模型调整到MINERvA包容中微子散射数据，包括核效应，如弱核屏蔽和两粒子，两个洞的增强。
We present double-differential measurements of antineutrino charged-current quasielastic scattering in the MINERvA detector. This study improves on a previous single-differential measurement by using updated reconstruction algorithms and interaction models and provides a complete description of observed muon kinematics in the form of a double-differential cross section with respect to muon transverse and longitudinal momentum. We include in our signal definition zero-meson final states arising from multinucleon interactions and from resonant pion production followed by pion absorption in the primary nucleus. We find that model agreement is considerably improved by a model tuned to MINERvA inclusive neutrino scattering data that incorporates nuclear effects such as weak nuclear screening and two-particle, two-hole enhancements.
