自旋为1/2的重子在多种味态下的反常维数QCD

The anomalous dimension of spin-1/2 baryons in many flavors QCD

Luca Vecchi

摘要:

本文用最小减法方法导出了QCD中自旋为1/2的重子算符在1/Nf阶的反常维数。残余的模糊性,源于存在的倏逝算子在维正则化,参数化的函数的重正化耦合。我们的结果表明,同意与以前的2和3圈计算在两个不同的重整化方案。

英文摘要:

The anomalous dimension of spin-1/2 baryon operators in QCD is derived at leading 1/Nf order using the minimal subtraction scheme. A residual ambiguity, originating from the presence of evanescent operators in dimensional regularization, is parametrized by a function of the renormalized coupling. Our result is shown to agree with previous 2 and 3 loop calculations performed in two different renormalization schemes.
