${\rm Y}(6S)$ and triangle singularity in $e^{+}{e}^{-}\to B_1(5721)\bar{B}\to Z_b(10610)\pi$

A. E. Bondar, M. B. Voloshin

We discuss the possibility that production of final states with bottomonium and light mesons at the peak ${\rm Y}(6S)$ in the $e^{+}{e}^{-}$ annihilation at approximately 11.00 GeV is in fact…
