Abstract

We present the first calculation within lattice QCD of excited light meson resonances with JPC=1J^{PC} = 1^{--}, 22^{--} and 33^{--}. Working with an exact SU(3) flavor symmetry, for the singlet representation of pseudoscalar-vector scattering, we find two 11^{--} resonances, a lighter broad state and a heavier narrow state, a broad 22^{--} resonance decaying in both PP- and FF-waves, and a narrow 33^{--} state. We present connections to experimental ωJ,ϕJ\omega^\star_J, \phi^\star_J resonances decaying into πρ\pi \rho, KKˉK\bar{K}^*, ηω\eta \omega and other final states.
