Abstract
We present lattice results on the scalar ${D}_{s}$ meson and comment on the ${D}_{\mathrm{sJ}}^{+}(2317)$ state recently discovered by BaBar and confirmed by CLEO, in view of a series of theoretical claims and counterclaims. Lattice predictions in the static limit indicate larger masses than observed for a scalar quark model state. Finite c quark mass corrections seem to further enlarge this discrepancy, in support of a non-quark-antiquark-state interpretation of experiment.
