论文摘要
我们认为，非局部夸克 - 易能公园和gluon操作员的重新归一化因子在太空状以及由威尔逊线与扰动理论中的所有顺序相吻合的时间样分离。我们分别将夸克式和Gluon算子的异常尺寸和重新归一化常数分别计算为三环准确性，还将这些操作员的真空期望值计算为三环准确度。
We argue that the renormalization factors for nonlocal quark-antiquark and gluon operators at space-like and time-like separations connected by a Wilson line coincide to all orders in perturbation theory. We calculate the anomalous dimensions and renormalization constants of quark-antiquark and gluon operators to three- and two-loop accuracy, respectively, and also compute vacuum expectation values of these operators to three-loop accuracy.
