Description
A fundamental step in the ALPHA collaboration efforts to
determine the fundamental parameters of QCD at the electroweak
scale in terms of hadronic quantities is the connection of an
intermediate scale with a hadronic scale. In this talk we will
show that using the Gradient Flow running coupling this task can be
achieved with a very high precision. Our analysis will pay special
attention to the continuum limit of flow quantities and reach a
precision below 2% in the scale factor for a change of the coupling
from to .
