Abstract
We study the spectrum and isospin-violating strong decays of charmed mesons with strangeness. The scalar Ds0â(2317)± and the axial-vector Ds1â(2460)± states are generated by coupled-channel dynamics based on the leading order chiral Lagrangian. The effect of chiral corrections is investigated. We show that taking into account large-Nc relations implies a measurable signal for an exotic axial-vector state in the ηDâ invariant mass distribution. The hadronic decay widths of the scalar Ds0â(2317)± and the axial-vector Ds1â(2460)± are predicted to be 140 keV.
