Gauge-fixing parameter dependence of two-point gauge-variant correlation functions.
The gauge-fixing parameter ξ dependence of two-point gauge variant correlation functions is studied for QED and QCD. We show that, in three Euclidean dimensions, or for four-dimensional thermal gauge theories, the usual procedure of getting a general covariant gauge-fixing term by averaging over a class of covariant gauge-fixing conditions leads to a nontrivial gauge-fixing parameter dependence...
متن کاملGauge-invariant resummation formalism for two-point correlation functions.
The consistent description of unstable particles, renormalons, or other Schwinger–Dysontype of solutions within the framework of perturbative gauge field theories necessitates the definition and resummation of off-shell Green’s functions, which must respect several crucial physical requirements. A formalism is presented for resummation of off-shell twopoint correlation functions, which is mainl...
متن کاملGauge invariance, gauge-parameter independence and properties of Green functions
The application of the background-field method to the electroweak Standard Model is reviewed and further explored. Special emphasis is put on questions of gauge invariance and gauge-parameter (in-)dependence. Owing to the gauge invariance of the background-field effective action, the vertex functions obey simple Ward identities which imply important properties of the vertex functions. Carrying ...
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 کاملAbelian projection and studies of gauge-variant quantities in the lattice QCD without gauge fixing
We suggest a new (dynamical) Abelian projection of the lattice QCD. It contains no gauge condition imposed on gauge fields so that Gribov copying is avoided. Configurations of gauge fields that turn into monopoles in the Abelian projection can be classified in a gauge invariant way. In the continuum limit, the theory respects the Lorentz invariance. A similar dynamical reduction of the gauge sy...
