Revealing the inner structure of the newly observed $D_2^{\ast }(3000)$

Abstract

Stimulated by the recent observation of the $D_2^{\ast }(3000)$, we study the decay behaviors of the $3P$ and $2F$ charmed mesons in the present work. By comparing the masses and decay properties of the $3^3{P}_2$ and $2^3{F}_2$ charmed mesons with the observation of the $D_2^{\ast }(3000)$, we conclude that the most possible assignment of the $D_2^{\ast }(3000)$ is the $3^3{P}_2$ charmed meson, while the assignment of the $2^3{F}_2$ charmed meson could not be fully exclude. The results of the unobserved $3P$ and $2F$ charmed mesons in this work could provide some fundamental information of searching for these charmed mesons in the further experiments by LHCb and forthcoming Belle II.
