Description

I present our results for the computation of the non-perturbative renormalization and running of the renormalized quark masses in $N_f = 3$ QCD. Adopting finite-size scaling techniques, the running is computed from low energy scales $\sim \Lambda_{\rm QCD}$ to high energy $\sim M_W$. This large range of scales allows to make contact from one side with a "hadronic" renormalization scheme, and on the other with perturbation theory. The computation is carried out to very high precision, using massless $\mathcal{O}(a)$ improved Wilson quarks.
