在这项工作中，我们通过质谱分析和计算相应的二体强衰变行为来研究新观测到的$D_J(3000)$和$D_J^*(3000)$。我们的结果表明，$D_J(3000)$ 和 $D_J^*(3000)$ 分别被解释为 $D$ 介子族中的 $2P(1^+)$ 和 $2^3P_0$ 态，这得到了这两种态的计算质量及其衰变行为的支持。作为副产品，$3^1S_0$、$3^3S_1$、$2D(2^-)$、$2^3D_1$、$2D^\prime(2^-)$、$2^3D_3$、$2P^\prime(1^+)$、$2^3P_2$、$1F(3^+)$、$1^3F_2$、还给出了 $1F^\prime(3^+)$ 和 $1^3F_4$ 状态，这也将有助于进一步实验研究这些 $D$ 介子的混合。
In this work, we study the newly observed $D_J(3000)$ and $D_J^*(3000)$ through the analysis of mass spectrum and calculation of the corresponding two-body strong decay behaviors. Our results show that $D_J(3000)$ and $D_J^*(3000)$ are explained as the $2P(1^+)$ and $2^3P_0$ states in the $D$ meson family, respectively, which is supported by the calculated masses of these two states and their decay behaviors. As a byproduct, the decay behaviors of $3^1S_0$, $3^3S_1$, $2D(2^-)$, $2^3D_1$, $2D^\prime(2^-)$, $2^3D_3$, $2P^\prime(1^+)$, $2^3P_2$, $1F(3^+)$, $1^3F_2$, $1F^\prime(3^+)$, and $1^3F_4$ states are also given, which will be helpful to further experimentally study mixings of these $D$ mesons, too.
