Constraints on low energy QCD parameters from $$\eta \rightarrow 3\pi $$ η→3π and $$\pi \pi $$ ππ scattering
Abstract The $$\eta \,\rightarrow \,3\pi $$ η→3π decays are a valuable source of information on low energy QCD. Yet they were not used for an extraction of the three flavor chiral symmetry breaking order parameters until now. We use a Bayesian approach in the framework of resummed chiral perturbatio...
