Abstract

We present preliminary results for the charm quark mass in the Nf= 4 RGI scheme. These were obtained using Nf = 2 + 1 CLS ensembles with O(a) non-perturbatively improved Wilson fermions. We employed five different lattice spacings, ranging down to a. 0.04 fm and realized approximately physical pion and kaon masses, with ensembles spread out along three different trajectories in the quark mass plane, enabling a thorough study of the dependence on the lattice spacing and the light and strange sea quark masses. We sketch our analysis strategy and find that the dominant errors at present are due to the renormalization and scale setting uncertainties.
