Abstract

Based on the assumption that D_sJ ^*(2317) and D_sJ(2460) are the (0⁺,1⁺) chiral partners of D_s and D^* _s, we evaluate the strong pionic and radiative decays of D_sJ ^*(2317) and D_sJ(2460) in the constituent quark meson (CQM) model. Our numerical results of the relative ratios of the decay widths are reasonably consistent with the data.
