Description
The Large $N_c$ limit is often invoked in phenomenological approaches. Even though it is a useful simplification of QCD, the systematic uncertainties of these large-$N_c$-inspired approximations to QCD remain unclear. Moreover, it fails in some observables, such as the ratio of isospin amplitudes in the $K \to \pi \pi$ weak decays. In this context, lattice QCD has a lot of yet unexplored potential to shed light on the Nc scaling of these observables. I will review in this talk some of our recent results concerning weak decays, scattering parameters and meson decay constants at Large $N_c$ from lattice simulations.
