Description
We report the first determination of universal parameters of the axial a1(1260) resonance from lattice QCD [arXiv:2107.03973 [hep-lat] in press at PRL]. Three-body quantization condition (FVU) is generalized and utilized to extract infinite-volume information from lattice eigenenergies. Subsequently, pole position and residua of the three-body resonance are extracted on the second Riemann sheet. Results are compared to the phenomenological ones.
