- ItemDetermination of quark and gluon vacuum condensates from τ-lepton decay data(1988) Dominguez, C. A.; Solà, J.The values of the gluon and four-quark vacuum condensates are estimated using recent experimental data on the semileptonic ?-lepton decays ??v?+n?, which determine the vector and axialvector hadronic spectral functions. An optimal estimate is achieved through a systematic combined use Finite Energy, Laplace and Gaussian transform QCD sum rules. As a byproduct, the values of the dimensiond=8 vacuum condensates in the vector and axial-vector channels are also estimated.
- ItemDetermination of the gluon condensate and the four quark condensate via FESR(1988) Bertlmann, R. A.; Dominguez, C. A.; Loewe Lobo, Marcelo Patricio; Perrottet, M.; de Rafael, E.The dimension four gluon condensate and the dimension six four-quark condensate are estimated with the help of FESR by analyzing the ?-meson channel. We find that the first is a factor 2 5 and the second is (in absolute value) a factor 5 8 larger than the corresponding standard values. We have checked our results by the heat evolution test of Gauss transforms. They turn out to be consistent whereas the standard values are not.

- ItemInverse magnetic catalysis from the properties of the QCD coupling in a magnetic field(2016) Loewe Lobo, Marcelo Patricio; Ayala, A.; Dominguez, C. A.; Hernandez, L.; Zamora Jofré, Renato Andrés
- ItemLocal 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.

- ItemTensor 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.
