We extend an earlier calculation within lattice QCD of excited light meson resonances with JPC=1−−,2−−,3−− at the SU(3) flavor point in the singlet representation, by considering the octet representation. In this case the resonances appear in coupled-channel amplitudes, which we determine, establishing the relative strength of pseudoscalar-pseudoscalar to pseudoscalar-vector decays. Combining the new octet results with the prior results for the singlet, we perform a plausible extrapolation to the physical quark mass, and compare to experimental ρJ⋆,KJ⋆,ωJ⋆ and ϕJ⋆ resonances.
