标题： Remarks on the Gauge Dependence of the RI/MOM Renormalization Procedure

摘要： 在SU(3)冻结QCD中使用威尔逊费米子研究了RI/MOM非微扰重整化方案在格点上的情况。通过比较在两种不同的朗道规范实现和一种一般协变规范中规范固定的数据显示，讨论了一些费米子双线性量重整化常数的规范依赖性。各种结果集与理论之间非常好的一致性表明，由格点规范固定过程引起的数值不确定性适中，并低于统计误差。 显示英文摘要

摘要： The RI/MOM non-perturbative renormalization scheme is studied on the lattice in SU(3) quenched QCD with Wilson fermions. The gauge dependence of some fermion bilinear renormalization constants is discussed by comparing data which have been gauge-fixed in two different realizations of the Landau gauge and in a generic covariant gauge. The very good agreement between the various sets of results and the theory indicates that the numerical uncertainty induced by the lattice gauge-fixing procedure is moderate and below the statistical errors.
