一个大质量动量相减方案
A massive momentum-subtraction scheme
摘要：
我们引入了一个新的大规模重整化计划，表示为mS的，作为现有的RI/S的计划的修改。我们用S_∞来定义非零费米子质量下QCD中的重整化费米子双线性。该方案具有类似于Sunday方案的性质，例如使用非例外对称动量，而与Sunday相反，它定义了远离手征极限的重整化场。在这里，我们讨论的一些性质的mS的，并提出非微扰参数导出一些重整化常数。一维正则化的1-循环计算的结果进行了简要总结，以说明该计划的一些性质。
英文摘要：
We introduce a new massive renormalization scheme, denoted mSMOM, as a modification of the existing RI/SMOM scheme. We use SMOM for defining renormalized fermion bilinears in QCD at non-vanishing fermion mass. This scheme has properties similar to those of the SMOM scheme, such as the use of non-exceptional symmetric momenta, while in contrast to SMOM, it defines the renormalized fields away from the chiral limit. Here we discuss some of the properties of mSMOM, and present non-perturbative arguments for deriving some renormalization constants. The results of a 1-loop calculation in dimensional regularization are briefly summarised to illustrate some properties of the scheme.
