Strong decays of the charmed mesons $D_1^{\ast }(2680)$, $D_3^{\ast }(2760)$, $D_2^{\ast }(3000)$

Abstract

In this article, we assign the higher charmed mesons $D_1^{\ast }(2680)$, $D_3^{\ast }(2760)$ and $D_2^{\ast }(3000)$ to be the 2S $1^{-}$, 1D $3^{-}$ and 1F $2^{+}$ states, respectively, and study the two-body strong decays to the ground state charmed mesons and light pseudoscalar mesons with the heavy meson effective theory. We obtain the ratios among the strong decays, which can be confronted to the experimental data in the future and shed light on the nature of those higher charmed mesons.
