Gauge Fixing Identity in the Background Field Method of QCD in Pure Gauge
Gouranga C Nayak ∗ 1 Department of Physics, University of Arizona, Tucson, AZ 85721, USA Abstract In this paper we derive a gauge fixing identity by varying the covariant gauge fixing term in Z[A, J, η, η̄] in the background field method of QCD in pure gauge. Using this gauge fixing identity we establish a relation between Z[J, η, η̄] in QCD and Z[A, J, η, η̄] in background field method of QCD in ...
متن کاملResidual Gauge Fixing in Light-Front QCD
Understanding the nontrivial features of light-front QCD is a central goal in current investigations of nonperturbative light-front field theory. We find that, with the choice of light-front gauge with antisymmetric boundary conditions for the field variables, the residual gauge freedom is fixed and the light-front QCD vacuum is trivial. The nontrivial structure in light-front QCD is determined...
متن کاملGauge fixing by unitary transformations in QCD
The unitary gauge fixing technique is applied to the QCD hamiltonian formulated in terms of angular variables. It is demonstrated that in this formulation projections on the physical Hilbert space are unnecessary to separate physical and unphysical degrees of freedom. Therefore the application of the unitary gauge fixing technique can be extended to the operator level.
متن کاملSpinodal decomposition in pure-gauge QCD
Spinodal decomposition in a model of pure-gauge SU(2) theory that incorporates a deconfinement phase transition is investigated by means of real-time lattice simulations of the fully nonlinear Ginzburg-Landau equation. Results are compared with a Glauber dynamical evolution using Monte Carlo simulations of pure-gauge lattice QCD.
متن کاملNon-fixing Gauge Field Quantization
The gauge field theories are usually quantized by fixing gauge. In this paper, we propose a new formalism that quantizes gauge fields without gauge fixing but naturally follows canonical formalism. New physical implications will follow. Gauge symmetry is often indispensable because relativistic system usually need gauge symmetry. If it were not for gauge symmetry for a vector or tensor field, w...
