Existing Data

In previous works effective nonlocal SU (2)× SU (2) NJL model was proposed in which all the parameters are expressed through those of the fundamental QCD: current light quark mass m0 and average nonperturbative αs. The results for scalar and pseudoscalar mesons are in satisfactory correspondence to existing data. In the present work the same model without introduction of any additional parameters is applied for a description of masses and strong decay widths of ρ- and a1-mesons. The results for both scalar and vector sectors agree with data up to accuracy of the model.

Rule Method

The method of QCD sum rules at finite temperature is reviewed, with emphasis on recent results. These include predictions for the 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.
