Tri-meson-mixing of $\pi$-$\eta$-${\eta }^{\prime }$ and $\rho$-$\omega$-$\varphi$ in the light-cone quark model

Abstract

The radiative transition form factors of the pseudoscalar mesons {$\pi$, $\eta$, ${\eta }^{\prime }$} and the vector mesons {$\rho$, $\omega$, $\varphi$} are restudied with $\pi$-$\eta$-${\eta }^{\prime }$ and $\rho$-$\omega$-$\varphi$ in tri-meson-mixing pattern, which is described by tri-mixing matrices in the light-cone constituent quark model. The experimental transition decay widths are better reproduced with tri-meson-mixing than previous results in a two-mixing-angle scenario of only two-meson $\eta$-${\eta }^{\prime }$ mixing and $\omega$-$\varphi$ mixing.
