Mixing angles and electromagnetic properties of ground state pseudoscalar and vector meson nonets in the light-cone quark model

Both the mass spectra and the wave functions of the light pseudoscalar (π, K, η, η') and vector(ρ, K*, ω, φ) mesons are analyzed within the framework of the light-cone constituent quark model. A Gaussian radial wave function is used as a trial function of the variational principle for a QCD motivated Hamiltonian which includes not only the Coulomb plus confining potential but also the hyperfine interaction to obtain the correct ρ - π splitting. The mixing angles of ωw - φ and η - η' are predicted and various physical observables such as decay constants, charge radii, and radiative decay rates etc. are calculated. Our numerical results have a good agreement with the available experimental data. (author)
