Abstract

The vector and axial-vector two-point functions are calculated to next-to-next-to-leading order in Chiral Perturbation Theory for three light flavours. We also obtain expressions at the same order for the masses, m² _π, m² _Κ and m² _η, and the decay constants, F_π, F_Κ and F_η. We present some numerical results after a simple resonance estimate of some of the new O(p⁶) constants.
