Explaining the anomalous $��(5S)\to ��_{bJ}��$ decays through the hadronic loop effect

DOI

Description

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