Determination of Low-Energy Constants of Wilson Chiral Perturbation Theory
Abstract
By matching Wilson twisted mass lattice QCD determinations of pseudoscalar meson masses to Wilson Chiral Perturbation Theory we determine the low-energy constants W'6, W'8 and their linear combination c2. We explore the dependence of these low-energy constants on the choice of the lattice action and on the number of dynamical flavours.
