Laplacian gauge gluon propagator in SU „

Lattice QCD provides a well suited theoretical framework for the study of nonperturbative quantities as a function of the number of colors. Although experimentally inaccessible, QCD for Nc52 and Nc54 is interesting from the theoretical point of view. Recently SU(Nc) Yang-Mills theories were investigated for various Nc by two groups @1,2# with emphasis on the evaluation of string tensions and gl...

Infrared Behavior of the Gluon Propagator in Lattice Landau Gauge

We evaluate numerically the four-momentum-space gluon propagator in lattice Landau gauge, for pure SU(2) lattice gauge theory with periodic boundary conditions. Simulations are done in the strong-coupling regime, namely at β = 0, 0.8, 1.2 and 1.6, and for lattice sizes up to 30, 16, 20 and 24 respectively. In the limit of large lattice volume, we observe in all cases a gluon propagator decreasi...

Gluon 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...

Analytic structure of the Landau-gauge gluon propagator.

The analytic structure of the nonperturbative gluon propagator contains information on the absence of gluons from the physical spectrum of the theory. We study this structure from numerical solutions in the complex momentum plane of the gluon and ghost Dyson-Schwinger equations in Landau gauge Yang-Mills theory. The resulting ghost and gluon propagators are analytic apart from a distinct cut st...

The Landau gauge lattice QCD simulation and the gluon propagator

In 1978 Gribov showed that the fixing of the divergence of the gauge field in non-Abelian gauge theory does not fix its gauge[1]. The restriction of the gauge field such that its Faddeev-Popov determinant is positive (Gribov region) is necessary yet insufficient for excluding the ambiguity. The restriction to the fundamental modular region[2,4] cancels the infrared singularity of the perturbati...
