Lattice QCD data versus Chiral Perturbation Theory: the case of Mπ
I present a selection of recent lattice data by major collaborations for the pseudo-Goldstone boson masses in full (Nf =2) QCD, where the valence quarks are chosen exactly degenerate with the sea quarks. At least the more chiral points should be consistent with Chiral Perturbation Theory for the latter to be useful in extrapolating to physical masses. Perspectives to reliably determine NLO Gass...

These are the proceedings of the workshop on “Lattice QCD, Chiral Perturbation Theory and Hadron Phenomenology” held at the European Centre for Theoretical Studies in Nuclear Physics and Related Areas from October 2 to 6, 2006. The workshop concentrated on bringing together researchers working in lattice QCD and chiral perturbation theory with the aim of improving our understanding how hadron p...
متن کاملApplications of chiral perturbation theory to lattice QCD
These notes contain the written version of lectures given at the 2009 Les Houches Summer School “Modern perspectives in lattice QCD: Quantum field theory and high performance computing.” The goal is to provide a pedagogical introduction to the subject, and not a comprehensive review. Topics covered include a general introduction, the inclusion of scaling violations in chiral perturbation theory...

متن کاملMatching Current Correlators in Lattice QCD to Chiral Perturbation Theory
Chiral perturbation theory gives direct and unambiguous predictions for the form of various two-point hadronic correlators at low momentum in terms of a finite set of couplings in a chiral Lagrangian. In this paper we study the feasibility of extracting the couplings in the chiral Lagrangian (through 1-loop order) by fitting two-point correlators computed in lattice QCD to the predicted chiral ...
