We calculate the collinear anomalous dimensions in massless four-loop QCD and N=4 supersymmetric Yang-Mills theory from the infrared poles of vertex form factors. We give very precise numerical approximations and a conjecture for the complete analytic results in both models we consider.

QCD 中的四环共线异常维度和 N=4 超级杨米尔斯

我们计算了无质量四环 QCD 中的共线异常维度和 N=4来自顶点形状因子的红外极点的超对称杨米尔斯理论。对于我们考虑的两种模型中的完整解析结果,我们都给出了非常精确的数值近似值和猜想。
