Search for $XYZ$ states in ${\rm Y}\left(1S\right)$ inclusive decays

The branching fractions of the ${\rm Y}\left(1S\right)$ inclusive decays into final states with a $J/\psi$ or a $\psi \left(2S\right)$ are measured with higher precision to be $B\left({\rm Y}\right(1S)\to J/\psi +\text{anything})=(5.25\pm 0.13(\mathrm{stat})\pm 0.25(\mathrm{syst}\left)\right)\times {10}^{-4}$ and $B\left({\rm Y}\right(1S)\to \psi (2S)+\text{anything})=(1.23\pm 0.17(\mathrm{stat})\pm 0.11(\mathrm{syst}\left)\right)\times {10}^{-4}$. The first search for ${\rm Y}\left(1S\right)$ decays into $XYZ$ states that decay into a $J/\psi$ or a $\psi \left(2S\right)$ plus one or two charged tracks yields no significant signals for $XYZ$ states in any of the examined decay modes, and upper limits on their production rates in ${\rm Y}\left(1S\right)$ inclusive decays are determined.
