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 ($\pi,K,\eta,\eta'$) and vector($\rho,K^{*},\omega,\phi$) 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 harmonic oscillator potential but also the hyperfine interaction to obtain the correct $\rho-\pi$ splitting. The mixing angles of $\omega-\phi$ and$\omega-\phi$ and $\eta-\eta'$ are predicted and various physical observables such as decay constants, charge radii, and radiative decay rates $etc.$ are calculated. Our numerical results are in a good agreement with the available experimental data.
