摘要：

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, m(pi)(2), m(K)(2) and m(eta)(2) and the decay constants, F-pi, F-K and F-eta. We present some numerical results after a simple resonance estimate of some of the new O(p(6)) constants. (C) 2000 Elsevier Science B.V. All rights reserved.
