Explaining the anomalous ${\rm Y}(5S)\to {\chi }_{bJ}\omega$ decays through the hadronic loop effect

Abstract

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