Description
Understanding hadron interactions from QCD is key to mapping out the resonance spectrum of the strong interaction. In recent years, lattice QCD has made significant progress in treating both two- and three-body scattering, but a description of coupled systems involving both remains lacking.
In this talk, we present a study of the isoscalar vector sector in a coupled two- and three-body framework. Building on our previous investigation of the $\pi\pi\pi$ channel, we extend the analysis to include $K\bar{K}$ states and study $\omega$-$\phi$ mixing within the finite-volume unitarity (FVU) formalism. We extract finite-volume spectra and scattering amplitudes, and discuss the resulting pole structure and mixing parameters.
