论文摘要
我们计算了SU（4） - 单元的非平面异常尺寸的非平面贡献。分析形式的任意Lorentz自旋的通用异常维度。至于浅色尖端异常维度和通用异常尺寸的$ζ_5$的一部分，我们确认了先前的结果。
We compute the nonplanar contribution to the universal anomalous dimension of the SU(4)-singlet twist-two operators in N=4 supersymmetric Yang-Mills theory at four loops through Lorentz spin 18. From this, we numerically evaluate the nonplanar contribution to the four-loop lightlike cusp anomalous dimension and derive the transcendental $ζ_3$ and $ζ_5$ parts of the universal anomalous dimension for arbitrary Lorentz spin in analytic form. As for the lightlike cusp anomalous dimension and the $ζ_5$ part of the universal anomalous dimension, we confirm previous results.
