Figure 17. Compilation of data for the pion-nucleon coupling constant g (cid:25)NN from experi- ment (A-M) and from lattice simulations (N-Q). We do not discriminate between charged and neu- tral pion-nuclon couplings here, which can be slightly di(cid:11)erent. In the lattice section we have only listed direct determinations, ignoring all results that are merely based on the Goldberger-Treiman relation [151]. Extractions based on a dipole ansatz are colored red, while those using any variant of the z -expansion are colored blue. Some lattice calculations use an EFT ansatz colored green (a pion pole term combined with a Taylor expansion). The error bands show the results of our !2P (red) and our ! z 4+3 (blue) (cid:12)ts, with all errors added in quadrature. The lattice result in parentheses is outdated, cf. the discussion in ref. [73]. For a recent review, see ref. [152]. Symbols: circle:
