通过衰减模式识别$D_{sJ}(2700)$

Identifying $D_{sJ}(2700)$ through its decay modes

P. Colangelo, F. De Fazio, S. Nicotri, M. Rizzi

摘要:

通过分析最近观测到的$D_{sJ}(2700)$介子的末态衰变模式,研究了如何将其分配到$c \bar s$谱的合适能级上.我们使用一个有效的拉格朗日方法与重夸克和手征对称性,获得的测量的$D^* K$衰变宽度将允许区分两种可能的分配。

英文摘要:

We study how to assign the recently observed $D_{sJ}(2700)$ meson to an appropriate level of the $c \bar s$ spectrum by the analysis of its decay modes in final states comprising a light pseudoscalar meson. We use an effective lagrangian approach with heavy quark and chiral symmetries, obtaining that the measurement of the $D^* K$ decay width would allow to distinguish between two possible assignments.
