Description

We study the strong and radiative decays of the antiquark-quark ground state nonet{ρ3(1690),K⋆3(1780),ϕ3(1850),ω3(1670)} in the framework of an effective quantum field theory approach, based on the SUV(3) flavor symmetry. The effective model is fitted
to experimental data listed by the Particle Data Group . We predict numerous experimentally
unknown decay widths and branching ratios. An overall agreement of theory (fit and predictions)
with experimental data confirms the qq¯¯ nature of the states and qualitatively validates the effective
approach.
