摘要
我们给出了来自杰斐逊实验室 E00-110 实验的深度虚康普顿散射（DVCS）区和价夸克区中光子电产生（）截面的最后结果。之前已发表这些数据的子集分析结果，但此处详细描述了改进的分析以及实验装置的细节。此外，分析了额外数据，得到了新运动学设置下的光子电产生截面，总计 588 个实验 bin。讨论了螺旋度相关和螺旋度无关截面的 和 依赖性结果。 依赖性说明了如前所述的实验运动学中 twist-2 手袋振幅的主导地位。由于该高亮度实验的优异精度，清楚地表明非极化截面在我们的运动学中与 Bethe-Heitler 过程显著偏离，这与主导 twist-2 DVCS 项对光子电产生截面的巨大贡献相一致。还讨论了为完全重现数据形状而包含高阶扭转修正的必要性。本文中的 DVCS 截面代表了 E00-110 的最终实验结果集，取代了之前的出版物。
