Light and strange quark masses from $N_f=2+1$ simulations with Wilson fermions

We present a preliminary analysis of the $u/d$ and $s$ quark masses, extracted using the PCAC quark masses reported in PRD 95 (2017) 074504. The data is based on the CLS $N_f = 2 + 1$ simulations with Wilson/Clover quarks and Lüscher-Weisz gauge action, at four $\beta$ values (i.e. lattice spacings) and a range of quark masses. We use the Alpha results of EPJC 78 (2018) 387 for non-perturbative quark mass renormalisation and RG-running from hadronic to electroweak scales in the Schrödinger Functional scheme. Quark masses are quoted both in the $\overline{MS}$ scheme and as RGI quantities.
