Structure of $X_{b}$ from line shape analysis

Yue Ma, Guo-Ying Chen

We study the production line shape of $B^{*} B ˉ$ near threshold, where the $B^{*} B ˉ$ pair comes from the resonance $X_{b}$ . Our study shows that the line shape depends sens…

The nature of $Z_{b}$ states from a combined analysis of $Υ (5 S) \to h_{b} (m P) π^{+} π^{-}$ and $Υ (5 S) \to B^{()} B ˉ^{()} π$

Wen-Sheng Huo, Guo-Ying Chen

With a combined analysis of data on $Υ (5 S) \to h_{b} (1 P, 2 P) π^{+} π^{-}$ and $Υ (5 S) \to B^{(*)} B ˉ^{(*)} π$ in an effective field theory approach, we determine resona…
