Abstract
Assuming that the ϒ(10753) is a 4S−3D mixed state, we investigated the hidden-bottom hadronic decays of the ϒ(10753)→ηb(1S)ω(η(′)) via the intermediate meson loops. In a commonly accepted range of the model parameter α 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 ϒ(10753)→ηbη(′) to ϒ(10753)→ηbω is found to be dependent on the η−η′ mixing angle. In addition, we also calculated the ratios of the partial decays widths of the ϒ(10753)→ηbω to ϒ(10753)→ϒ(nS)π+π− (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 ϒ(10753) as the 4S−3D mixture. We hope these predictions could be verified by the future Belle II experiments. Published by the American Physical Society 2024
