Description

We present the first calculation within lattice QCD of excited light meson resonances with $J^{PC}=1^{--},2^{--}$, and $3^{--}$. We work within exact SU(3) flavor symmetry in the singlet representation and observe two $1^{--}$ resonances (a first in LQCD), a lighter broad state and a heavier narrower state, a broad $2^{--}$ resonance decaying in both P- and F-waves which is presently unobserved in experiment, and a narrow $3^{--}$ state. We present connections to the experimental $\omega^*_J$, $\phi^*_J$ resonances decaying into the physical states $\pi\rho$, $K\bar{K}^*$, $\eta\omega$ and others.
