标题： Two--Body Decays of $B_s$ Mesons

摘要： 我们使用Bauer-Stech-Wirbel模型计算了$B_s$介子在多个独占的两体衰变通道中的衰变率。 研究了模型自由参数对预测结果的影响。 发现$B_s$进入仅包含稳定带电粒子的末态的总分支比约为$10^{-3}$。 显示英文摘要

摘要： We have calculated the decay rates of the $B_s$ meson in a number of exclusive two--body decay channels using the Bauer--Stech--Wirbel model for current matrix elements. The influence of the free parameters of the model on the predictions is studied. The total branching ratio of the $B_s$ into final states which only contain stable charged particles is found to be about $10^{-3}$.
