QCD中可重整化规范不变非定域胶子质量算符的三圈MSbar反常维数

Three loop MSbar anomalous dimension for renormalizable gauge invariant non-local gluon mass operator in QCD

F. R. Ford, J. A. Gracey

摘要:

在MSbar格式下计算了胶子规范不变、可重整化、非定域质量算符的三圈反常维数。此外,还导出了相应的局域鬼场的反常维数,并证明了三圈QCD β函数是由胶子局域鬼点重整化正确地产生的。

英文摘要:

The three loop anomalous dimension for the gauge invariant, renormalizable, non-local mass operator for a gluon is computed in the MSbar scheme. In addition the anomalous dimensions of the associated localizing ghost fields are also deduced at the same order and it is shown that the three loop QCD beta-function correctly emerges from the gluon localizing ghost vertex renormalization.
