We study O++ (gg) channel in the framework of the Gauss-Weierstrass QCD sum rules. The results of this analysis definitely support the existence of a scalar gluonium bound state. Concerning the parameters of such a state, the case of a light and very narrow glueball turns out to be strongly favoured over that of a heavy and broad resonance.
