Study on Decays of $D_{sJ}^{\ast }(2317)$ and $D_{sJ}(2460)$ in terms of the CQM Model

Abstract

Based on the assumption that $D_{sJ}^{\ast }(2317)$ and $D_{sJ}(2460)$ are the $(0^{+},1^{+})$ chiral partners of $D_s$ and $D_s^{\ast }$, we evaluate the strong pionic and radiative decays of $D_{sJ}^{\ast }(2317)$ 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 data.
