Cornering Large-$N_c$ QCD with Positivity Bounds

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 meson...
