A possible gateway to eta_b: chi_{b0}(2P) -> eta eta_b

Abstract

It is argued that the branching ratio for the decay chi_{b0}(2P) -> eta eta_b can reach few permil as a result of the enhancement of the eta emission by the axial anomaly in QCD. This might make the discussed process practical for an experimental search for the eta_b.
