A Canonical Ds Spectrum.

Quark mass dependence induced by one loop corrections to the Breit-Fermi spin-dependent one gluon exchange potential permits an accurate determination of heavy-light meson masses. In this model, the Ds(2317), Ds(2460) and the newly discovered Ds(2700) and Ds(2860) are canonical cs mesons. The multiplet splitting relationship of chiral doublet models, M(1+) - M(1-) = M(0+) - M(0-), holds to good accuracy in the D and Ds systems, but is accidental. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR]
