A possible gateway to ηb: χb0(2P) → ηηb

Research output: Contribution to journalArticlepeer-review

9 Scopus citations


It is argued that the branching ratio for the decay χb0(2P) → ηηb can reach few permil as a result of the enhancement of the η emission by the axial anomaly in QCD. This might make the discussed process practical for an experimental search for the ηb.
