Determination of low energy constants and testing chiral perturbation theory at order p6 (NNLO)
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 ππ, πK scattering and Kl4 decay which have been evaluated numerically using fit 10 in  for the NLO LECs. We also show some preliminary results for a new global fit of the NLO LECs.
