Non-perturbative renormalization by decoupling

We propose a new strategy for the determination of the QCD coupling. It relies on a coupling computed in QCD with Nf≥3 degenerate heavy quarks at a low energy scale μdec, together with a non-perturbative determination of the ratio Λ/μdec in the pure gauge theory. We explore this idea using a finite...
