矢量介子第一径向激发态质量谱的研究

Mass Spectrum of the First Radial Excited Vector Meson States

在Regge唯象下计算了径向激发态23S1矢量多重态的介子质量.K*(1 410)作为23S1多重态的K*'(23S1)介子很不合理,建议在1 586 MeV能量附近寻找和研究K*'介子,分别在2.587,5.813,5.925,6.895 GeV能量附近寻找和研究D*'(23S1),B*'(23S1),B*'s(23S1),B*'c(23S1)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(23S1)矢量介子和进一步研究其自旋-宇称安排有一定的意义.

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.
