Determination of Low Energy Constants and testing Chiral Perturbation Theory at Next to Next to Leading Order
Author
Summary, in English
We present the results of a search for relations between
observables that are independent of the Chiral Perturbation Theory (ChPT)
Next-to-Next-to-Leading Order (NNLO) Low-Energy Constants (LECs). We have found
some relations between observables in $\pi\pi$, $\pi K$ scattering and
$K_{l4}$ decay which have been evaluated numerically using the old fit (fit 10
in~\cite{Amoros:2001cp}) of the
NLO LECs.
