Assuming that the ϒ ( 10753 ) is a 4 S − 3 D mixed state, we investigated the hidden-bottom hadronic decays of the ϒ ( 10753 ) → η b ( 1 S ) 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 ) → η b η ( ′ ) to ϒ ( 10753 ) → η b ω 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 ) → η b ω to ϒ ( 10753 ) → ϒ ( n S ) 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 4 S − 3 D mixture. We hope these predictions could be verified by the future Belle II experiments.
