Abstract

In this work, we study the hadronic loop contribution to the ϒ(5S)ϒ(13DJ)η (J=1, 2, 3) transitions. We predict that the branching ratios of ϒ(5S)ϒ(13D1)η, ϒ(5S)ϒ(13D2)η, and ϒ(5S)ϒ(13D3)η can reach up to (0.55.1)×103, (0.77.5)×103 and (0.99.6)×104, respectively. Since these predicted hadronic transitions of ϒ(5S) are comparable with these observed ϒ(5S)ϒ(nS)π+π (n=1, 2, 3), we suggest for future experiments like Belle and BelleII to carry out the search for these anomalous ϒ(5S)ϒ(13DJ)η transitions.
