从线形分析看$X_b$的结构
Structure of $X_b$ from line shape analysis
摘要：
我们研究了$B^\ast\bar B$在阈值附近的产生线形状，其中$B^\ast \bar B$对来自于共振$X_b$。我们的研究表明，线的形状敏感地依赖于结合能和在物理束缚态中找到基元态的概率。这两个参数对于鉴定$X_b$的结构都是至关重要的。因此，线形测量可以揭示$X_b$的结构。
英文摘要：
We study the production line shape of $B^\ast\bar B$ near threshold, where the $B^\ast \bar B$ pair comes from the resonance $X_b$. Our study shows that the line shape depends sensitively on the binding energy and the probability of finding an elementary state in the physical bound state. Both of the two parameters are crucial to identify the structure of $X_b$. Therefore, the line shape measurement can shed light on the structure of $X_b$.
