论文摘要
我们介绍了RI' - （S）MOM方案的非扰动计算，用于QCD量规场合的QCD仪表集合，由Cls（协调的晶格模拟）努力产生，并具有三种非扰动的Wilson（Clover）Quarks的三种口味。我们在时间方向上使用标准（反）周期性边界条件的合奏以及具有开放边界条件的量规场配置。除了最多有两个衍生物的Quark-Antiquark运算符，我们还考虑具有多达一个衍生物的三夸克操作员。对于RI'-SMOM方案结果，我们利用最近计算出的三环转换因子到修改的最小减法方案。本文的当前版本包含附录，并带有其他分析表达式和更新的结果。
We present the nonperturbative computation of renormalization factors in the RI'-(S)MOM schemes for the QCD gauge field ensembles generated by the CLS (coordinated lattice simulations) effort with three flavors of nonperturbatively improved Wilson (clover) quarks. We use ensembles with the standard (anti-)periodic boundary conditions in the time direction as well as gauge field configurations with open boundary conditions. Besides flavor-nonsinglet quark-antiquark operators with up to two derivatives we also consider three-quark operators with up to one derivative. For the RI'-SMOM scheme results we make use of the recently calculated three-loop conversion factors to the modified minimal subtraction scheme. The present version of the paper contains an Addendum with additional analytical expressions and updated results.
