The difficulty in the decay constants and spectra of $D_{sJ}^{\ast }$

Abstract

We examine the compatibility in predicted masses and the decay constants of $D_{sJ}^{\ast }$ mesons in terms of two-quark contents. We find that the results of a specific model, which is governed by heavy quark limit, will encounter a challenge to fit both spectra and decay constants simultaneously.
