Abstract

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 [1] for the NLO LECs. We also show some preliminary results for a new global fit of the NLO LECs.
