χc decays and the gluon component of the η′, η mesons
The large mass of the η′ meson indicates that a sizeable gluon component is present in the meson wave function. However, the χc0 and χc2 decays 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 re...
