根据质量劈裂公式计算了轴矢介子多重态(11P1)中底偶素的质量,然后利用粒子表上最新的实验数据,在雷吉唯象的框架下计算轴矢介子多重态中双重介子Bc1、奇异偶素(ss-bar和奇异介子K1B的质量. 最后在介子-介子混合的框架下,计算了K1A - K1B混合角和轴矢介子九重态中两个同位旋标量态的混合角. 我们建议实验上在1478 MeV能量附近进一步研究轴矢介子h1(1380)的性质,在6774 MeV能量附近寻找和研究轴矢介子Bc1(1P).本文的计算结果对于实验上寻找还没有观测到的双重介子态Bc1以及理解K1A - K1B混合和轴矢介子九重态的混合有一定的意义.In this work, using the formula for hyperfine splittings, we first calculate the mass of the bottomonium member for the axial-vector multiplet (11P1). Then, the masses of the axial-vector mesons Bc1,(ss and K1B are extracted in Regge phenomenology. After that, we estimate the nonet mixing angle and the mixing angle for K1A - K1B. We suggest restudying h1(1380) near 1478 MeV and searching Bc1(1P) near 6774 MeV. The predictions may be useful for the discovery of the unobserved doubly heavy meson Bc1 and useful for understanding the K1A - K1B mixing and the axial-vector (11P1) nonet mixing.
