Abstract

We present preliminary results in the charm sector from a mixed-action setup, in which CLS $N_f=2+1$ ensembles are combined with a Wilson twisted mass valence action. We study the continuum and chiral limits of charm quark observables such as the decay constants $f_{D_{(s)}}$ and the renormalized charm-quark mass.
