Lattice 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 کاملAbelian and Nonabelian Lattice Chiral Gauge Theories through Gauge Fixing
After an introduction in which we review the fundamental difficulty in constructing lattice chiral gauge theories, we summarize the analytic and numerical evidence that abelian lattice chiral gauge theories can be nonperturbatively constructed through the gauge-fixing approach. In addition, we indicate how we believe that the method may be extended to nonabelian chiral gauge theories.
متن کاملLattice 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 کاملGribov Copies and Gauge Fixing in Lattice Gauge Theories
The formulation of gauge theories on the lattice does not require gauge fixing. However, to study Green’s functions of the fundamental fields, it is unavoidable to pick a gauge. Moreover, the correlation functions of the fundamental fields can be used to compute renormalization constants or non-perturbative coefficients used in numerical simulations. For a general overview on gauge fixing in la...
متن کاملNon-gauge fixing approach to chiral gauge theories using staggered fermions
We investigate a proposal for the construction of models with chiral fermions on the lattice using staggered fermions. In this approach the gauge invariance is broken by the coupling of the staggered fermions to the gauge fields. Motivated by previous results in the non-gauge invariant massive Yang-Mills theory and certain gauge-fermion models we aim at a dynamical restoration of the gauge inva...
