- 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.

- ItemFinite Temperature QCD Sum Rules: A Review(2017) Ayala, Alejandro; Dominguez, C. A.; Loewe, M.The method of QCD sum rules at finite temperature is reviewed, with emphasis on recent results. These include predictions forthe survival of charmonium and bottonium states, at and beyond the critical temperature for deconfinement, as later confirmed by lattice QCD simulations. Also included are determinations in the light-quark vector and axial-vector channels, allowing analysing the Weinberg sum rules and predicting the dimuon spectrum in heavy-ion collisions in the region of the rho-meson. Also, in this sector, the determination of the temperature behaviour of the up-down quark mass, together with the pion decay constant, will be described. Finally, an extension of the QCD sum rule method to incorporate finite baryon chemical potential is reviewed.
- 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.
