Explaining the anomalous \(\Upsilon(5S)\to \chi_{bJ}\omega\) decays through the hadronic loop effect

Abstract

In this work, we carry out the study on \(\Upsilon(5S)\to \chi_{bJ}\omega\) (\(J=0,1,2\)) by considering the hadronic loop mechanism. Our results show that the Belle's preliminary data of the branching ratios for \(\Upsilon(5S)\to \chi_{bJ}\omega\) can be well reproduced in our calculation with a common parameter range, which reflects the similarity among these \(\Upsilon(5S)\to \chi_{bJ}\omega\) decays of concern.
