Vector meson $\omega$-$\phi$ mixing and their form factors in light-cone quark model

TL;DR

This paper investigates the $ ext{ω}$-$ ext{ϕ}$ meson mixing using light-cone quark models, comparing one- and two-mixing-angle scenarios across different schemes to match experimental data and form factor behaviors.

Contribution

It provides a comparative analysis of mixing schemes and angles, demonstrating the effectiveness of the two-mixing-angle scenario in modeling meson mixing and form factors.

Findings

Two-mixing-angle scenario fits experimental data well.

One-mixing-angle scenario performs better in the quark flavor scheme.

Difference between mixing angles varies across schemes.

Abstract

The vector meson $\omega$-$\phi$ mixing is studied in two alternative scenarios with different numbers of mixing angles, i.e., the one-mixing-angle scenario and the two-mixing-angle scenario, in both the octect-singlet mixing scheme and the quark flavor mixing scheme. Concerning the reproduction of experimental data and the $Q^2$ behavior of transition form factors, one-mixing-angle scenario in the quark flavor scheme performs better than that in the octet-singlet scheme, while the two-mixing-angle scenario works well for both mixing schemes. The difference between the two mixing angles in the octet-singlet scheme is bigger than that in the quark flavor scheme.
