摘要:

考虑到粲介子丰富的实验信息和目前的研究现状,本文通过分析粲介子族的质量谱和计算它们的OZI允许衰变行为,系统地研究了粲介子族中的高次径向和轨道激发.这一唯象分析不仅揭示了新观测到的粲态$D(2550)$、$D^*(2600)$、$D^*(2760)$、$D(2750)$、$D_J(2580)$、$D^*_J(2650)$、$D^*_J(2760)$、$D_J(2740)$、$D_J(3000)$和$D^*_J(3000)$的基本性质,而且提供了实验中尚缺少的粲介子的有价值的信息.

英文摘要:

Considering abundant experimental information of charmed mesons and the present research status, in this work we systematically study higher radial and orbital excitations in the charmed meson family by analyzing the mass spectrum and calculating their two-body OZI-allowed decay behaviors. This phenomenological analysis not only reveals underlying propertes of the newly observed charmed states $D(2550)$, $D^*(2600)$, $D^*(2760)$, $D(2750)$, $D_J(2580)$, $D^*_J(2650)$, $D^*_J(2760)$, $D_J(2740)$, $D_J(3000)$ and $D^*_J(3000)$, but also provides valuable information of the charmed mesons still missing in experiments.
