Description
We report on first computations of hadron masses and matrix elements with
charm quarks in O$(a)$ improved (2+1)-flavour lattice QCD in the framework of
stabilised Wilson Fermions.
Employing SU(3)-flavour-symmetric gauge field ensembles from the OpenLAT initiative, we study two strategies how to fix the physical charm quark mass.
In a first approach, we follow the standard procedure by matching to a physical meson mass such as the D-meson mass. In our new approach we implement a massive
renormalisation scheme that is designed to reduce mass-dependent cutoff
effects. The latter requires the determination of certain
improvement coefficients and renormalisation constants around the heavy
quark mass scale which is also discussed in this contribution.
