Cornering large-N c QCD with positivity bounds

Abstract The simple analytic structure of meson scattering amplitudes in the large-N c limit, combined with positivity of the spectral density, provides precise predictions on low-energy observables. Building upon previous studies, we explore the allowed regions of chiral Lagrangian parameters and m...
