Coupled-channel meson resonances from lattice QCD
Journal Article

· Physical Review. D.
We extend an earlier calculation within lattice QCD of excited light meson resonances with at the 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 and resonances.
