Lattice Chiral Gauge Theories
I review the substantial progress which has been made recently with the non-perturbative construction of chiral gauge theories on the lattice. In particular, I discuss three different approaches: a gauge invariant method using fermions which satisfy the Ginsparg–Wilson relation, and two gauge non-invariant methods, one using different cutoffs for the fermions and the gauge fields, and one using...
متن کاملLattice Gauge Theories
We review some analytic results on the deconfinement transition in pure lattice gauge theories. In particular we discuss the relationship between the deconfinement transition in the (d + 1)-dimensional SU(2) model and the magnetization transition in the d-dimensional Ising model. This analysis leads to a precise estimate of the deconfinement temperature which agrees well with that obtained with...
متن کاملLattice Chiral Gauge Theories through Gauge Fixing
After an introduction in which we review the fundamental difficulty in constructing lattice chiral gauge theories, we discuss the analytic and numerical evidence that abelian lattice chiral gauge theories can be non-perturbatively constructed through the gauge-fixing approach. While a complete non-abelian extension is still under construction, we also show how fermion-number violating processes...
متن کاملLattice Gauge Theories at Large
We investigate the lattice gauge theory with fermions at infinite coupling and show that, after formal integration over the fermion fields, it reduces to the Wilson pure gauge theory in the limit when the number of fermion flavours nf approaches infinity. When the boson fields are integrated over instead, the action describes a local theory of Fermi fields only. For finite nf the ferrnion actio...
متن کاملSupersymmetric quiver gauge theories on the lattice
In this paper we detail the lattice constructions of several classes of supersymmetric quiver gauge theories in two and three Euclidean spacetime dimensions possessing exact supersymmetry at finite lattice spacing. Such constructions are obtained through the methods of topological twisting and geometric discretization of Euclidean Yang-Mills theories with eight and sixteen supercharges in two a...
