摘    要:在Regge唯象下计算了径向激发态2^3S1矢量多重态的介子质量.K^*(14-10)作为2^3S1多重态的K^*’(2^3S1)介子很不合理,建议在1586MeV能量附近寻找和研究K^*'介子,分别在2.587,5.813,5.925,6.895GeV能量附近寻找和研究D”(2。S。),B”(2^3S1),占?12。S。),B?’(2。S,)介子.研究结果对于通过实验寻找尚未观测到的径向激发态(2^3S1)矢量介子和进一步研究其自旋一宇称安排有一定的意义.

关 键 词:Regge唯象  矢量介子  质量谱

Abstract:Based on the Regge phenomenology, the masses of radial excited vector mesons (23S1 multi- plet) were calculated. K* (1 410) was unreasonable to be the K*' (23Sl) state. It was suggested that K* '(23S1) should be searched near 1 586 MeV, and also suggested that D* '(23SI ), B* '(23S1 ), Bs* '(23S1 ) and Bc* '(23S1 ) should be searched near 2. 587, 5. 813, 5. 925 and 6. 895 GeV, respective- ly. The results might be useful to search the undiscovered first radial excited vector mesons and the JP as- signment of them.
Keywords:Regge phenomenology  vector meson  mass spectrum
