E12-14-012实验是在杰斐逊实验室A厅进行的，用天然的Ar靶测量了平行运动学中的横截面。在这里，我们报告了对应于束能量2.222 GeV，并跨越丢失动量和丢失能量范围的数据集的完整分析结果。用蒙特卡罗模拟的结果拟合了作为模型谱函数并包括终态相互作用影响的约化截面，该截面是精确的函数。数据和模拟之间的总体一致性证明是令人满意的()。由此得到的光谱函数将提供有价值的新信息，这些信息对于解释液态Ar探测器中的中微子相互作用是必要的。
The E12-14-012 experiment, performed in Jefferson Lab Hall A, has measured thecross section in parallel kinematics using a natural argon target. Here, we report the full results of the analysis of the data set corresponding to beam energy 2.222 GeV, and spanning the missing momentum and missing energy rangeand. The reduced cross section, determined as a function ofandwithaccuracy, has been fitted using the results of Monte Carlo simulations involving a model spectral function and including the effects of final state interactions. The overall agreement between data and simulations turns out to be quite satisfactory (). The resulting spectral function will provide valuable new information, needed for the interpretation of neutrino interactions in liquid argon detectors.
