摘要: 基于实验上已经确认的基态张量介子九重态的安排和现有的实验数据，利用从雷吉轨迹理论和质量混合矩阵推导出的介子质量关系，对张量介子第一径向激发态的安排做了分析预测．根据得到的结果，可以推测f2（1810）和f2（2010）可能作为张量介子第一径向激发态的候选者．同时给出了f2（1810）和f2（2010）作为张量介子第一径向激发态时的衰变信息．这些结论对激发态张量介子，特别是其中的同位旋标量态的安排将提供帮助．Abstract: In the view of the experimentally confirmed existence of the a2 (1325), f2 (1525), f2 (1270) and K2* (1430), which are the ground tensor meson 13P2 members, through combining the Regge trajectory and meson mass mixing matrix, we investigate the assignment of the first radial excitation of tensor meson. We suggest that the states f2 (1810) and f2 (2010) should be the candidates of this assignment. Moreover, some information about decaying of f2 (1810) and f2 (2010), which serve as pseudoscalar mesons, are presented. The results should be tested in the experiment in the future.
