Hidden-bottom hadronic transitions of $\mathrm{{\rm Y}}(10753)$

Assuming that the $\mathrm{{\rm Y}}(10753)$ is a $4S$-$3D$ mixed state, we investigated the hidden-bottom hadronic decays of the $\mathrm{{\rm Y}}(10753)\to {\eta }_b(1S)\omega ({\eta }^{(\mathrm{\prime })})$ via the intermediate meson loops. In a commonly accepted range of the model parameter $\alpha$ in the form factor, the predicted branching ratios may reach to the order of ${10}^{-3}$–${10}^{-2}$. The relative ratio of the partial decay widths of the $\mathrm{{\rm Y}}(10753)\to {\eta }_b{\eta }^{(\mathrm{\prime })}$ to $\mathrm{{\rm Y}}(10753)\to {\eta }_b\omega$ is found to be dependent on the $\eta$-${\eta }^{\mathrm{\prime }}$ mixing angle. In addition, we also calculated the ratios of the partial decays widths of the $\mathrm{{\rm Y}}(10753)\to {\eta }_b\omega$ to $\mathrm{{\rm Y}}(10753)\to \mathrm{{\rm Y}}(nS){\pi }^{+}{\pi }^{-}$ ($n=1,2$), which are found to be around 0.4 and 0.2 for $n=1$ and $n=2$, respectively. These values are in accordance with the preliminary experimental results. The calculations presented here tend to favor the $\mathrm{{\rm Y}}(10753)$ as the $4S$-$3D$ mixture. We hope these predictions could be verified by the future BelleII experiments.
