    Local duality constraints on scalar gluonium
    (1986) Dominguez, C. A.; Paver, N.
    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.

    Tensor gluonium spectrum in QCD
    (1986) Dominguez, C. A.; Paver, N.
    We examine the 2++ gluonium spectrum in the framework of the Gauss-Weierstrass and Finite Energy QCD sum rules. The results of our analysis support the interpretation of the ?(1710) as a tensor glueball, but they also suggest the existence of at least another state with a massM?2 GeV and a width of about 200 MeV.
