Abstract	We present results showing that Domain Wall fermions are a suitable discretisation for the simulation of heavy quarks. This is done by a continuum scaling study of charm quarks in a M\"obius Domain Wall formalism using a quenched set-up. We find that discretisation effects remain well controlled by the choice of Domain Wall parameters preparing the ground work for the ongoing dynamical $2+1f$ charm program of RBC/UKQCD.

$Left: Determination of the lattice spacing with the Sommer scale parameter $r_0$ and flow parameter $t_0$ as a cross check of the determination of the lattice spacing. Right: $\log{a}$ as a function of $\beta$ to determine finite size effects. The larger symbols correspond to the 4 ensembles used for measurements, the smaller to the auxiliary ensembles with volumes of $1.23-1.89\mathrm{fm}$.$ $Left: Determination of the lattice spacing with the Sommer scale parameter $r_0$ and flow parameter $t_0$ as a cross check of the determination of the lattice spacing.

The data is normalised at $m^\mathrm{norm}_\mathrm{PS} = 1.5\mathrm{GeV}$ (horizontal and vertical green dotted lines) to avoid finding a renormalisation constant. The vertical red line corresponds to the $\eta_c$ mass. Right: Overlay of data from the two coarsest ensembles for 3 choices of $M_5$. The dotted (dashed) curves depict data from the (second) coarsest ensemble.$ Show more plots
