Lattice gauge-fixing for generic covariant gauges
We propose a method which allows the generalization of the Landau lattice gauge-fixing procedure to generic covariant gauges. We report preliminary numerical results showing how the procedure works for SU(2) and SU(3). We also report numerical results showing that the contribution of finite lattice-spacing effects and/or spurious copies are relevant in the lattice gauge-fixing procedure.
متن کاملNew Covariant Gauges in String Field Theory
A single-parameter family of covariant gauge fixing conditions in bosonic string field theory is proposed. It is a natural string field counterpart of the covariant gauge in the conventional gauge theory, which includes the Landau gauge as well as the Feynman (Siegel) gauge as special cases. The action in the Landau gauge is largely simplified in such a way that numerous component fields have n...

متن کاملSoft covariant gauges on the lattice.
In recent years, hadron spectroscopy has become the most popular field of application of lattice QCD. Hadron masses, decay constants, and matrix elements for semileptonic decays are routinely computed from Green functions of composite hadron fields and expectation values of current operators between hadron states. However, the predictive power of lattice QCD is not limited to these kinds of cal...
متن کاملCasimir Energy in Non-covariant Gauges
The zero-point energy of a conducting spherical shell is studied by imposing the axial gauge via path-integral methods, with boundary conditions on the electromagnetic potential and ghost fields. The coupled modes are then found to be the temporal and longitudinal modes for the Maxwell field. The resulting system can be decoupled by studying a fourth-order differential equation with boundary co...
