论文摘要
在这项工作中，我们通过考虑使用HADRONE LOOP机制来研究$υ（10753）\ to到达（NS）π^+π^ - $（$ n = 1,2,3 $）的过程，其中$ 4S $ -3D $混合计划中的常规底池分配了$υ（10753）$。我们相关过程的结果具有相当大的分支比率，可以达到$ 10^{ - 4} -10^{ - 3} $的数量级。我们应该指出，测得的$γ_{e^+e^ - } \ times \ Mathcal {b} [υ（10753）\toυ（ns）π^+π^ - ] $值可以很好地复制。这一事实支持了前底元分配给$ 4S $ - $ 3D $混合方案中的$υ（10753）$。显然，如果可以进一步测试这项工作的预测结果，那么这是一个正在进行的Belle II实验的好机会。
In this work, we investigate the $Υ(10753)\toΥ(nS)π^+π^-$ ($n=1,2,3$) 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 $Γ_{e^+e^-}\times\mathcal{B}[Υ(10753)\toΥ(nS)π^+π^-]$ 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.
