Numerical Study of the Gluon Propagator in Lattice Landau Gauge: the Three-Dimensional Case

Abstract

We study the infrared behavior of the gluon propagator in lattice Landau gauge, for pure SU(2) lattice gauge theory in a three-dimensional lattice. Simulations are done for nine different values of the coupling $\beta$, from $\beta =0$ (strong coupling) to $\beta =6.0$ (in the weak-coupling region). In the limit of large lattice volumes, we observe in all cases a gluon propagator decreasing as the momentum goes to zero.
