Description
We present a study of the charmed meson and baryon ground state spectra
on the electrically neutral subset of the BMW $N_f=2+1+1$ gauge
configurations that utilise the 3-HEX smeared clover action. The
analysis focuses on a systematic evaluation of the hyperfine
mass splittings of the doubly charmed $J/\psi$ and $\eta_{c}$ mesons and
the singly charmed $D_s^*$ and $D_s$ mesons, with the aim to understand
the significant cut-off effects that can accompany Wilson type
fermion measurements.
