The gluonic B and J/psi decays into the eta' meson
Harald Fritzsch ; Yu-Feng Zhou ;

Journal Phys.Rev. D68 (2003) 034015
Subject hep-ph
AbstractThe inclusive and exclusive B decays into the eta’ meson plus others are investigated in a model based on the QCD anomaly. The invariant mass distribution is discussed. The constraint of the effective coupling is obtained from the data of the exclusive decay modes. The branching ratio of J/psi -> eta’eta gamma is predicted to be as large as 5.4*10^{-5}, which can be tested in the forthcoming CLEO-c experiments.
