论文摘要
我们确定横向操作员的异常尺寸矩阵，将大量夸克风味$ n_f $限制为总导数运算符，以在$ \ overline {\ text {ms}}} $ - 方案中的强耦合$α_s$中的第四顺序。这是通过使用操作员异常尺寸之间的一致性关系来实现的，这是从操作员在手性极限下的重新归一化结构遵循的。
We determine the anomalous dimension matrix for the transversity operator mixing into total derivative operators in the limit of a large number of quark flavors $n_f$ to fourth order in the strong coupling $α_s$ in the $\overline{\text{MS}}$-scheme. This is achieved by using a consistency relation between the operator anomalous dimensions, which follows from the renormalization structure of the operators in the chiral limit.
