Abstract

We report on our simulations with Neuberger valence fermions on CLS N_f=2 configurations with non-perturbatively O(a)-improved Wilson sea quarks. We consider the matching of QCD to ChPT in the so called mixed-regime in which the sea quarks are in the p-regime while the valence quarks are in the ε-regime. From this matching, we can get information on Σ, L₆ and the combination L₈+2L₆+2L₇.
