A Canonical Ds(2317)?

Abstract

It is shown that quark mass dependence induced by one loop corrections to the Breit-Fermi spin-dependent one gluon exchange potential permit an accurate determination of heavy-light meson masses. Thus the $D_s(2317)$ is a canonical $c\bar{s}$ meson in this scenario. The multiplet splitting relationship of chiral doublet models, $M(1^{+})-M(1^{-})=M(0^{+})-M(0^{-})$, holds to good accuracy in the $D$ and $D_s$ systems, but is accidental. Radiative transitions and bottom flavoured meson masses are discussed.
