K-l4 form-factors and pi-pi scattering

The F and G form-factors of K-l4 and the quark condensates are calculated t o O(p(6)) in Chiral Perturbation theory (CHPT). Full formulas are presented as much as possible. A full real of most of the O(p(4)) CHPT parameters is done with a discussion of all inputs and underlying assumptions. We discus s the consequences for the vacuum expectation values, decay constants, pseu doscalar masses and pi-pi scattering. (C) 2000 Elsevier Science B.V. All ri ghts reserved.
