摘　　要：系统地研究了相对论夸克模型框架下的底奇异介子的辐射衰变。给出了底奇异介子E1和M1辐射衰变分宽度。这些结果表明,大多数电偶极辐射衰变宽带能达到数个ke V,大多数磁偶极辐射衰变宽度小于1个ke V,这为实验上通过辐射衰变寻找底奇异介子提供了理论依据。建设中的Belle II上的实验可以进一步验证我们的结果。We systematically study the radiative transitions of bottom-strange mesons in the framework of the relativistic constituent quark model.＂ The partial widths of the E1 and M1 decays are predicted The results predict that most of E1 decay widths are several keV and mosi of M1 decay widths are less than i keV,which give a roadmap of searching for the higher bottom-strange mesons via radiative decays The experimental searches by the forthcoming Belle II can in turn provide further tests to our result in the present work.
