Abstract

In this work, we investigate the Υ(10753)→Υ(1³D_J)η (J=1,2,3) processes, where the Υ(10753) is assigned as a conventional bottomonium under the 4S-3D mixing scheme. Our result shows that the concerned processes have considerable branching ratios, \it i.e., branching ratios B[Υ(10753)→Υ(1³D₁)η] and B[Υ(10753)→Υ(1³D₂)η] can reach up to the order of magnitude of 10^-4-10^-3, while B[Υ(10753)→Υ(1³D₃)η] is around 10^-6-10^-5. With the running of Belle II, it is a good opportunity for finding out the concerned hidden-bottom hadronic decays.
