论文摘要

为了帮助晶格场理论的匹配与高能连续限制的结果,我们评估了绿色的功能,在Q Quark双线性操作员以Quark $ 2 $ 2 $ 2 $ 2 $ 2 $ 2 $ 2 $ 2的功能插入任意协值仪的功能。这是在MSBAR和RI'方案中进行的四个循环。在两种方案中,对于任意颜色组的两个方案中,张量电流异常维度也被计算为四个循环。

To assist the matching of lattice field theory results to the high energy continuum limit we evaluate the Green's function where the tensor quark bilinear operator is inserted at zero momentum in a quark $2$-point function for an arbitrary covariant gauge. This is carried out in both the MSbar and RI' schemes to four loops. The tensor current anomalous dimension is also calculated to four loops in both schemes for an arbitrary colour group.
