This will be an abbreviated version of the course, with the selection of topics to be made according to the wishes of the students. The complete course is described below. The aim of the course is to describe non-perturbative approaches to non-Abelian gauge theories. Our main physical problem is quark confinement.

The lattice provides a cutoff for field theory which permits many manipulations beyond the reach of Feynman-diagram perturbation theory. We will exploit exact transformations among different field theories and use topological methods and duality to study the physics of these theories. After introducing the lattice formulation of QCD, we will develop techniques by using simpler field theories as laboratories: the Ising model, the XY or planar Heisenberg model, the Ising gauge theory due to Wegner , the Abelian gauge theory related to QED.

The problem of taking the continuum limit will bring us to the study of critical points and the renormalization group. The lattice has also provided the easiest approach to numerical calculation in field theory. We will describe the basics of Monte Carlo methods and show how the qualitative ideas presented above find quantitative realization in these calculations. The foremost practical problem standing in the way of the calculation of hadron properties is also the most interesting open theoretical problem: how to put fermion field theories on the lattice.

We will review this long-standing problem and current attempts to solve it.

Curator: Peter Weisz. Citation Scholar Bot. Carlo Maria Becchi. Lattice gauge theory is a formulation of quantum field theory with gauge symmetries on a space-time lattice. This formulation is particularly suitable for describing hadronic phenomena. In this article we review the present status of lattice QCD. We outline some of the computational methods, discuss some phenomenological applications and a variety of non-perturbative topics.

This book provides a broad introduction to gauge field theories formulated on a space-time lattice, and in particular of QCD. It serves as a textbook for advanced graduate students, and also provides the reader with the necessary analytical and numerical techniques to carry out research on his own. Although the analytic calculations are sometimes quite demanding and go beyond an introduction, they are discussed in sufficient detail, so that the reader can fill in the missing steps. The book also introduces the reader to interesting problems which are currently under intensive investigation.
