In large-Nc chiral perturbation theory, the decay constant depends on a single correlated combination of F0, L4, and C16, so phenomenological fits constrain directions rather than independent low-energy constants.

Correlated low-energy constants in large-$N_c$ chiral perturbation theory
In large-Nc chiral perturbation theory, the decay constant depends on a single correlated combination of F0, L4, and C16, so phenomenological fits constrain directions rather than independent low-energy constants.
