摘要
我们在QCD的淬火近似下,计算了手征改进格点费米子的费米子双线性算符的非微扰重整化常数。我们处理了有限尺寸效应和Gribov副本的影响。我们的结果以RI'和MSbar方案以及RGI形式给出,并讨论了手征对称性所隐含的重整化常数之间的关系。发表后,我们将(24)式中α_s^3第一系数的分子从3696847更正为3890527,这使得在μ=2 GeV处的转换系数值提高了0.2%。

备注
24 pages, 7 figures, final version, After publication we corrected the numerator of the first coefficient of \alpha_s^3 in (24) from 3696847 to 3890527, which yields a 0.2% higher value of the conversion coefficient at \mu=2 GeV
