The renormalization of the effective QCD-Hamiltonian theory for thequark-antiquark channel is performed in terms of a renormalized or fixed-pointHamiltonian that leads to subtracted dynamical equations. The fixedpoint-Hamiltonian brings the renormalization conditions as well as thecounterterms that render the theory finite. The approach is renormalizationgroup invariant. The parameters of the renormalized effective QCD-Hamiltoniancomes from the pion mass and radius, for a given constituent quark mass. The 1sand excited 2s states of $\bar u q$ are calculated as a function of the mass ofthe quark $q$ being s, c or b, and compared to the experimental values.Comment: 39 pages, 10 figure
