在CQM模型下研究D_（s1）~＊（2710）→D_（sJ）（1968,2112）＋π~0的强衰变

Study on strong decays of D_（s1）~＊（2710）→D_（sJ）（1968,2112）＋π~0 in CQM Model

伴随着新的D介子不断被发现,奇异介子的族谱也变得丰富起来,利用组份夸克模型研究了强衰变过程Ds*1(2710)→Ds(1968)+π0和Ds*1(2710)→Ds*(2112)+π0。讨论了Ds*1(2710)这个存在争议的粒子,计算结果支持它由c和s珋组成,属于H类型的双重态(0-,1-),自旋-宇称为JP=1-,js=1/2。这对粲介子族谱的研究有重要意义。

With the observation of new D mesons,the spectrum of the charmed-strange state becomes abundant.We investigated the strong decays of D＊s1（2710）→Ds（1968）＋π0 and D＊s1（2710）→D＊s（2112）＋π0 in the CQM model,and discussed the newly discovered meson D＊s1（2710）.Our numerical results suggest that the newly discovered meson belongs to H doublet（0-,1-） and is made up of c and,whose spin parity is JP=1-and js=1/2.It is very useful to the research of the charm spectroscopy.
