Description

Recently we introduced a new gradient flow based beta-function which is
defined over infinite Euclidean space-time to calculate and integrate
infinitesimal scale changes in RG flows. It can be applied in high-
precision determination of the strong coupling at the Z-pole in QCD. In
this talk we will discuss the results and challenges of the method
applied to quenched QCD ( pure Yang-Mill theory) as a pilot test for application to
full QCD.
