摘要
我们报告了三体 e+e- => B B-bar π、B B*-bar π 和 B* B*-bar π 过程的分析，包括首次观测到 Zb±(10610) => [B B*-bar+c.c.]+- 和 Zb±(10650) => [B*B*-bar]+- 跃迁。我们测量了三体产生的可见截面 σ_vis(e+e- => [B B*-bar+c.c.]+-pi-+=(11.2±1.0(stat.)±1.2(syst.)) pb 和 σ_vis(e+e- => [B*B*-bar]+-pi-+)=(5.61±0.73(stat.)±0.66(syst.)) pb，并设定了 σ_vis(e+e- => [BB-bar]+-pi-+)<2.1 pb 的 90% C.L. 上限。结果基于在质心能量靠近 Y(5S) 峰处用 Belle 探测器收集的 121.4 1/fb 数据样本。
