Continuum methods in lattice perturbation theory
We show how methods of continuum perturbation theory can be used to simplify perturbative lattice calculations. We use the technique of asymptotic expansions to expand lattice loop integrals around the continuum limit. After the expansion, all nontrivial dependence on momenta and masses is encoded in continuum loop integrals and the only genuine lattice integrals left are tadpole integrals. Usi...
متن کاملRenormalized Lattice Perturbation Theory
Apparent large failures of perturbation theory in lattice gauge theory at g* 5 1.0 result from the use of the bare coupling constant of the lattice regulator in the perturbative expansion. They can be cured by the use of a coupling constant defined by some physical process. Thissituation is thesame as that encountered in dimensionally regularized perturbation theory, where the use of a coupling...
متن کاملImproving lattice perturbation theory.
Lepage and Mackenzie have shown that tadpole renormalization and systematic improvement of lattice perturbation theory can lead to much improved numerical results in lattice gauge theory. It is shown that lattice perturbation theory using the Cayley parametrization of unitary matrices gives a simple analytical approach to tadpole renormalization, and that the Cayley parametrization gives lattic...
متن کاملLattice Perturbation Theory
Perturbation theory (PT) appears in many important theoretical and practical roles in lattice field theory. Conceptual issues related to the continuum limit can be studied in a perturbative framework, such as the renormalizability of lattice gauge theories [1]. Perturbative calculations are used in relating lattice quantities to those defined in continuum schemes and in constructing Symanzik-im...
متن کاملLattice QCD , Chiral Perturbation Theory
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...
