Applications of Chiral Perturbation theory to lattice QCD
arXiv:hep-lat/0607016
Abstract
These lectures describe the use of effective field theories to extrapolate results from the parameter region where numerical simulations of lattice QCD are possible to the physical parameters (physical quark masses, infinite volume, vanishing lattice spacing, etc.). After a brief introduction and overview, I discuss three topics: 1) Chiral perturbation theory in the continuum; 2) The inclusion of discretization effects into chiral perturbation theory, focusing on the application to Wilson and twisted-mass lattice fermions; 3) Extending chiral perturbation theory to describe partially quenched QCD.
