Lattice Quark Propagator in Landau and Laplacian Gauges
We present results for the lattice quark propagator in both Landau and Laplacian gauges using standard and improved staggered quark actions. The standard Kogut-Susskind action has errors of O(a) while the improved “Asqtad” action has O(a), O(ag) errors. This improvement is seen in the quark propagator. We demonstrate the application of tree-level corrections to these actions and see that Landau...
متن کاملLattice quark propagator with staggered quarks in Landau and Laplacian gauges
We report on the lattice quark propagator using standard and improved Staggered quark actions, with the standard, Wilson gauge action. The standard Kogut-Susskind action has errors of O(a) while the “Asqtad” action has O(a), O(ag) errors. The quark propagator is interesting for studying the phenomenon of dynamical chiral symmetry breaking and as a test-bed for improvement. Gauge dependent quant...
متن کاملResults on the Gluon Propagator in Lattice Covariant Gauges
We present preliminary data on the gluon propagator in generalized covariant gauges. The motivation for considering a generalized gauge-fixing procedure stems, just as in the continuum, from the necessity of studying the gauge dependence of the Green’s functions. In the covariant gauges it is possible to change the gauge fixing varying the value of the gauge parameter. In the continuum, the gen...
متن کاملGluon Propagator in the Landau Gauge Fixed Lattice Qcd Simulation
We measured the gluon propagator in the Landau gauge fixed QCD Langevin simulation[2] and studied the infra-red behaviour of the gluon propagator. The (43 × 8) lattice siulation was done for quenched β = 3, 4 and 5 and unquenched β = 4, κ = 0.1, 0.15 and 0.2, using each 100 independent samples. The Landau gauge fixing was done by an extension of the Fourier acceleration method with the conditio...
متن کاملQuark propagator from an improved staggered action in Laplacian and Landau gauges
Studies of gauge dependent quantities are afflicted with Gribov copies, but Laplacian gauge fixing provides one possible solution to this problem. We present results for the lattice quark propagator in both Landau and Laplacian gauges using standard and improved staggered quark actions. The standard Kogut-Susskind action has errors of O(a) while the improved “Asqtad” action has O(a), O(ag) erro...
