Relations at Order $p^6$ in Chiral Perturbation Theory

Abstract

We report on a search of relations valid at order $p^6$ in Chiral Perturbation Theory. We have found relations between $\pi \pi$, $\pi K$ scattering, $K_{\ell 4}$ decays, masses and decay constants and scalar and vector form factors. In this paper we give the relations and a first numerical check of them.
