Kℓ4 form-factors and π - π scattering

Amorós, G. ; Bijnens, J. LU orcid and Talavera, P. (2000) In Nuclear Physics B 585(1-2). p.293-352
Abstract

The F and G form-factors of Kℓ4 and the quark condensates are calculated to O(p6) in Chiral Perturbation theory (CHPT). Full formulas are presented as much as possible. A full refit of most of the 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.
