Identifying $D_{sJ}(2700)$ through its decay modes

Abstract

We study how to assign the recently observed $D_{sJ}(2700)$ meson to an appropriate level of the $c\bar{s}$ spectrum by the analysis of its decay modes in final states comprising a light pseudoscalar meson. We use an effective lagrangian approach with heavy quark and chiral symmetries, obtaining that the measurement of the $D^{\ast }K$ decay width would allow to distinguish between two possible assignments.
