  • 摘要:We present a method to automatically derive the Feynman rules for mesonic chiral perturbation theory with a lattice regulator. The Feynman rules can be output both in a human-readable format and in a form suitable for an automated numerical evaluation of lattice Feynman diagrams. The automated method signicantly simplies working with improved or extended actions. Some applications to the study of nite-volume effects will be presented.
