论文摘要
我们将三环非单词校正计算为光子Quark形式因素，以考虑到对光子和夸克质量的虚拟性的全部依赖性。我们以有效的方式将微分方程的方法与围绕常规点和奇异点的扩展相结合。这使我们能够在整个运动学范围内准确地获得大约八到十二位数字的形式因素的结果。
We compute the three-loop non-singlet corrections to the photon-quark form factors taking into account the full dependence on the virtuality of the photon and the quark mass. We combine the method of differential equations in an effective way with expansions around regular and singular points. This allows us to obtain results for the form factors with an accuracy of about eight to twelve digits in the whole kinematic range.
