QCD effective coupling constant and effective quark mass given in a mass-dependent renormalization
Jun-Chen Su, Lian-You Shan, Ying-Hui Cao
The QCD one-loop renormalization is restudied in a mass-dependent subtraction scheme in which the quark mass is not set to vanish and the renormalization point is chosen to be an a…

On mass-dependent subtraction and removal of the ambiguity in QED renormalization
Jun-Chen Su, Xue-Xi Yi, Ying-Hui Cao
The QED renormalization is restudied by using a mass-dependent subtraction which is performed at a time-like renormalization point. The subtraction exactly respects necessary physi…
