Chi(c) decays and the gluon component of the eta', eta mesons
The large mass of the η′meson indicates that a sizeable gluon component is present in the meson wave function. However, the χc0and χc2decays to η′mesons, which proceed via a purely gluonic intermediate state and we would therefore naïvely expect to be enhanced by such a component, are in fact relati...
