Abstract
I briefly review 1 the estimate of the gluonia masses, decay and mixings in QCD with massless quarks from QCD spectral sum rules and some low- energy theorems. The data in the 0++ channel can be explained with some maximal gluonium-quarkonium mixing schemes, which then suggest a large violation of the OZI rule, similar to the case of the η′ in the U(1) A sector.
