Quark-antiquark composite systems: the Bethe-Salpeter equation in the spectral-integration technique
Abstract
The Bethe-Salpeter equations for the light-quark composite systems, q q-bar, are written in terms of spectral integrals. For the q q-bar -mesons characterized by the mass M, spin J and radial quantum number n, the equations are presented for the following (n,M2)-trajectories: piJ, etaJ, aJ, fJ, rhoJ, omegaJ, hJ and bJ.
