Abstract
In this work, we introduce the hadronic loop contribution to explain the anomalous radiative transitions between and , which was recently observed by the Belle Collaboration. Our calculation shows that the hadronic loop mechanism associated with these known decay mechanisms can explain why there exist anomalous radiative transitions between and . This study deepens our understanding of the decay mechanism of higher bottomonium radiative decays.
