Study on production of exotic $0^{+}$ meson $D_{sJ}^{\ast }(2317)$ in decays of $\psi (4415)$

Abstract

The newly observed $D_{sJ}^{\ast }$ family containing $D_{sJ}^{\ast }(2317)$, $D_{sJ}(2460)$ and $D_{sJ}(2632)$ attracts great interests. Determining their structure may be important tasks for both theorists and experimentalists. In this work we use the heavy quark effective theory (HQET) and a non-relativistic model to evaluate the production rate of $D_{sJ}^{\ast }(2317)$ from the decays of $\psi (4415)$, and we find that it is sizable and may be observed at BES III and CLEO, if it is a p-wave excited state of $D_s(1968)$. Unfortunately, the other two members of the family cannot be observed through decays of charmonia, because of the constraints from the final state phase space.
