The ideal mixing departure in vector meson physics

Abstract.In this work we study the departure from the ideal $\phi$-$\omega$ mixing angle within the framework of the Nambu-Jona-Lasinio model. In this context we show that the flavor symmetry breaking is unable to produce the shifting of the ideal mixing. We found that a nonet symmetry breaking in the neutral vector sector is necessary to regulate the non-strange content of the $\phi$ meson. The phenomenology is well described by our proposal.
