Lattice 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...
متن کاملRegularization Methods in Chiral Perturbation Theory
Chiral lagrangians describing the interactions of Goldstone bosons in a theory possessing spontaneous symmetry breaking are effective, nonrenormalizable field theories in four dimensions. Yet, in a momentum expansion one is able to extract definite, testable predictions from perturbation theory. These techniques have yielded in recent years a wealth of information on many problems where the phy...
متن کاملChiral Pertubation Theory with Lattice Regularization
We study the structure and perform some explicit calculations for the power ultraviolet divergences and their renormalization in the Chiral Pertubation Theory with lattice regularization in 1 and 2 loops.
متن کاملLattice regularization of chiral gauge theories to all orders of perturbation theory
In the framework of perturbation theory, it is possible to put chiral gauge theories on the lattice without violating the gauge symmetry or other fundamental principles, provided the fermion representation of the gauge group is anomaly-free. The basic elements of this construction (which starts from the Ginsparg–Wilson relation) are briefly recalled and the exact cancellation of the gauge anoma...
متن کاملChiral perturbation theory for lattice QCD at O(a)
Chiral perturbation theory (χPT) is widely used in analyzing lattice QCD data. Since χPT describes continuum QCD one has to take the continuum limit first before fitting the lattice data to the analytic predictions of χPT. Unfortunately, lattice data for various lattice spacings is often not available in order to perform a reliable continuum extrapolation. Nevertheless, it is common practice to...
