摘要:

本文将高粲介子$D^*_1(2680)$、$D_3^*(2760)$和$D_2^*(3000)$分别指定为2S $1^-$、1D $3^-$和1F $2^+$态,并利用重介子有效理论研究了高粲介子到基态粲介子和轻赝标介子的两体强衰变.我们得到了强衰变之间的比值,这些比值可以用来与实验数据进行比较,从而揭示高粲介子的性质。

英文摘要:

In this article, we assign the higher charmed mesons $D^*_1(2680)$, $D_3^*(2760)$ and $D_2^*(3000)$ 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.
