Title: Coupled-channel J meson resonances from lattice QCD

Journal Article · · Physical Review. D.

We extend an earlier calculation within lattice QCD of excited light meson resonances with J P C = 1 , 2 , 3 at the S U ( 3 ) flavor point in the representation, by considering the 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 ρ J , K J , ω J and ϕ J resonances.
