| 摘 要： | 在π2(1 670),η2(1 870)和η2(1 645)属于11 D2介子九重态的前提下,利用质量矩阵和非相对论组分夸克模型,对同位旋二重态K(1 D2)的质量给予讨论,二者的结果符合的很好.在此基础上,利用混合模型估算出D波介子中K(1 D2)与K(3 D2)间的混合角约为零度.而后,通过3 P0衰变模型计算K2(1 770)和K2(1 820)的部分衰变信息并与PDG提供的实验数据进行比较,建议目前实验上提供的衰变信息还不足以确定二者的混合程度.

| Abstract: | In the presence of th π2(1 670),η2(1 870)and η2(1 645) being the members of the 11D2 meson nonet,based on the mass-squared matrix and the nonrelativistic constituent quark model,the mass of the isodoublet K(1D2) is estimated with a good agreement,Further,with the help of the above value,it is suggested that the mixing angle between K(1D2) and K(3D2) is about 0 degrees.Then,some decay widths of K2(1 770) and K2(1 820) are estimated by the 3P0 decay model.The mixing angle beween them is difficult to confirm resoting to compare the result of 3P0 decay model with the PDG datas. |
