Description
We present a preliminary analysis of the $u/d$ and $s$ quark masses, extracted using the PCAC quark masses reported in Phys. Rev. D 95, 074504. The data is based on the CLS $N_f = 2 + 1$ simulations with Wilson/Clover quarks and Luescher-Weisz gauge action, at four $\beta$ values (i.e. lattice spacings) and a range of quark masses. We use the Alpha results of Eur.Phys.J. C78 (2018)387 for non-perturbative quark mass renormalisation and RG-running from hadronic to electroweak scales in the Schroedinger Functional scheme. Quark masses are quoted both in the $\overline{MS}$ scheme and as RGI quantities.
