Abstract

In this work, we investigate the Υ(10753)→Υ(nS)π⁺π^- (n=1,2,3) processes by considering the hadronic loop mechanism, where Υ(10753) is assigned to a conventional bottomonium in the 4S-3D mixing scheme. Our results of the concerned processes own considerable branching ratios, which can reach up to the order of magnitude of 10^-4-10^-3. We should indicate that the measured Γ_e⁺e^-\timesB[Υ(10753)→Υ(nS)π⁺π^-] values given by Belle can be reproduced well. This fact supports the former bottomonium assignment to the Υ(10753) in the 4S-3D mixing scheme. Obviously, it is a good opportunity for the ongoing Belle II experiment if the predicted result in this work can be tested further.
