Abstract

The F and G form-factors of K_ℓ4 and the quark condensates are calculated to \cal O(p⁶) in Chiral Perturbation Theory (CHPT). Full formulas are presented as much as possible. A full refit of most of the \cal O(p⁴) CHPT parameters is done with a discussion of all inputs and underlying assumptions. We discuss the consequences for the vacuum expectation values, decay constants, pseudoscalar masses and π-π scattering.
