The Ideal Mixing Departure in Vector Meson Physics
Abstract
In this work we study the departure for the ideal φ-ω mixing angle in the frame of the Nambu-Jona-Lasinio model. We have shown that in that context, the flavour symmetry breaking is unable to produce the shifting in the mixing angle. We introduce a nonet symmetry breaking in the neutral vector sector to regulate the non-strange content of the φ meson. The phenomenon is well reproduced by our proposal.
