Descripción
The low-energy sector of the mesonic spectrum exhibits some features which may be understood in terms of the SO(4) symmetry contained in the QCD-Hamiltonian written in the Coulomb Gauge. In our previous work, we have shown that this is indeed the case when the Instantaneous Color-Charge Interaction (ICCI) is treated by means of nonperturbative many-body techniques. Continuing along this line of description, in this work we calculate the width of meson states belonging to the low portion of the spectrum (E < 1 GeV). In spite of the rather simple structure of the Hamiltonian used to calculate the spectra of pseudoscalar and vector mesons, the results for the width of these states follow the pattern of the data.
