A Canonical Ds(2317)?
Olga Lakhina ; Eric S Swanson ;
Date 1 Aug 2006
AbstractIt 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 $car s$ 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.
