Abstract

Mass spectra and radiative decay widths for qq̄ mesons taken from well-established results of the Particle Data Group are fit by the O(4) ↔ U(3) transitional theory of the U(4) vibron model. The results are compared with those of the O(4) limit of the theory and the quark potential model. The O(4) ↔ U(3) transitional theory seems to give a better description of the heavy qq̄ mesons, while the O(4) limit gives an accurate description of the light and strange qq̄ mesons.
