The DsJ(2317): what can the Lattice say?

Abstract

We present lattice results on the scalar $D_s$ meson and comment on the $D_{sJ}^{+}(2317)$ state recently discovered by BaBar and confirmed by CLEO, in view of a series of theoretical claims and counter claims. 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.
