Extended Data Fig. 2: Infinite-volume extrapolation of gA.
From: A per-cent-level determination of the nucleon axial coupling from quantum chromodynamics
a, The three data points correspond to the a ≈ 0.12 fm and mπ ≈ 220 MeV ensembles with mπL = {5.36, 4.30, 3.25}. The next-to-leading order (NLO) finite-volume dependence predicted from the model-averaged extrapolation (to all 16 data points) is shown by the green band, with the central value indicated by the dashed green curve. b, Model-averaged extrapolation with finite-volume-adjusted data (coloured points). The central values of the raw data are denoted by a small black dash and, in all but one case, lie within one standard deviation of the finite-volume-adjusted result. Uncertainties are one s.e.m.
