The gluonic decay of the b quark and the $\eta '$ meson
The inclusive decay of B-mesons into eta' + X is the consequence of the gluonic decay of the b-quark into an s-quark. As a result of the QCD anomaly this decay proceeds partly as the decay b --> s + eta', similar to b ---> s + J/psi. The hadronic recoiling system is found to have a r...
