论文摘要
该手稿介绍了针对$ e（x）$提取的最近CLA和CLAS12数据的新分析。该出版物受益于对以\ url {1405.7659}形式发表的较小初步数据集的原始分析。 我们提出了扭曲3 PDF的第一个点逐点提取。标量PDF，$ e（x）$是通过分析$ \ sinx_r $的数据的分析，用于在CLAS和CLAS12的半包含质子质子目标中生产的二二体生产的光束旋转不对称性。迪哈德龙的形式主义允许使用共线框架，因此要求最少的近似值和假设集。提取的PDF $ e（x）$具有洞察力，可洞悉毫无疑问的Quark-Gluon相关性的物理学，其第一个梅林矩与核子的标量电荷相关。我们表明，标量PDF的质子风味组合不是零$ 74 \％$ $的概率。
This manuscript presents the new analysis of recent CLAS and CLAS12 data aimed at the extraction of $e(x)$. This publication benefits from a proof-of-principle analysis of a smaller preliminary data set published in a preprint form in \url{1405.7659}. We present the first point-by-point extraction of a twist-3 PDF. The scalar PDF, $e(x)$, is accessed through the analysis of the data for the $\sinϕ_R$-moment of the beam-spin asymmetry for dihadron production in semi-inclusive DIS off proton target at CLAS and CLAS12. The dihadron formalism allows for use of collinear framework, hence calling for a minimal set of approximations and hypotheses. The extracted PDF $e(x)$ carries insights into the physics of the largely-unexplored quark-gluon correlations, and its first Mellin moment is related to the marginally-known scalar charge of the nucleon. We show that the proton flavor combination of the scalar PDF is non-zero at more than $74\%$ probability.
