Abstract: | We study the spectrum and isospin-violating strong decays of charmed mesons with strangeness. The scalar and the axial-vector 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- relations implies a measurable signal for an exotic axial-vector state in the ηD∗ invariant mass distribution. The hadronic decay widths of the scalar and the axial-vector are predicted to be 140 keV. |
