论文摘要

在Jefferson Lab Hall A中进行的E12-14-012实验测量了使用天然氩靶的$（E，E'P）$横截面。在这里，我们报告了对应于Beam Energy 2.222 GEV的数据集的分析的完整结果，并跨越缺失动量和缺失的能量范围$ 15 \ Lesssim P_M \ Lessim 300 $ MEV/C和$ 12 \ $ 12 \ LISHSIM E_M \ LISHSIM \ LISHSIM \ LISHSIM 80 $ MEV。使用涉及模型频谱功能的蒙特卡洛模拟的结果和最终状态相互作用的效果，已安装了$ \ $ 4 \％精度的缩写横截面，其$ p_m $和$ e_m $，$ \ $ 4 \％的精度已拟合。数据和仿真之间的总体协议非常令人满意（$χ^2 $/n.d.o.f. = 1.9）。所得的光谱函数将提供有价值的新信息，以解释液体氩检测器中的中微子相互作用。

The E12-14-012 experiment, performed in Jefferson Lab Hall A, has measured the $(e, e'p)$ cross 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 range $15 \lesssim p_m \lesssim 300$ MeV/c and $12 \lesssim E_m \lesssim 80$ MeV. The reduced cross section, determined as a function of $p_m$ and $E_m$ with $\approx$4\% accuracy, has been fitted using the results of Monte Carlo simulations involving a model spectral function and including the effects of final state interactions. The overall agreement between data and simulations turns out to be quite satisfactory ($χ^2$/n.d.o.f.=1.9). The resulting spectral function will provide valuable new information, needed for the interpretation of neutrino interactions in liquid argon detectors.
