The cancellation between off-shell two body forces and three body forces implies a tremendous simplification in the study of three body resonances in two meson-one baryon systems. While this can be done by means of Faddeev equations we provide an alternative and simpler derivation using just the chiral Lagrangian and the field re-parametrization invariance.

Coarse graining hadronic scattering
Coarse graining of hadronic scattering fixes long-range chiral dynamics above cutoff r_c and counts short-range parameters as N_Par = N_S × N_I × (p r_c)^2 / 2 for χ² fits with proper degrees of freedom.
