First Lattice Study of Ghost Propagators in SU ( 2 ) and SU ( 3 )
نویسنده
چکیده
We present a numerical study of the ghost propagators in Landau gauge for SU(2) and SU(3) gauge theories at β=2.7 and β=6.0, respectively. Analyzing different lattice sizes up to 32 4 , we find small finite size effects. Down to the smallest available momenta, we observe no evidence for dipole behaviour of the ghost propagators.

Comparing Pure Yang-mills Su(2) and Su(3) Propagators
The infrared behavior of gluon and ghost propagators in Yang-Mills gauge theories is of central importance for the understanding of confinement in QCD. While analytic studies using Schwinger-Dyson equations predict the same infrared exponents for the SU(2) and SU(3) gauge groups, lattice simulations usually assume that the two cases are different, although their qualitative infrared features ma...
متن کاملCorrelation of the Ghost and the Quark in the Lattice Landau Gauge QCD
Effects of the quark field on the ghost propagator of the lattice Landau gauge are investigated by using the unquenched SU(3) configurations produced by the MILC collaboration and compared with quenched gauge configurations of SU(2) first copy of the overrelaxation gauge fixing, the parallel tempering (PT) gauge fixing and quenched SU(3) 564 configurations. We measure the color symmetric and th...
متن کاملInfrared behavior of gluon and ghost propagators from asymmetric lattices
We present a numerical study of the lattice Landau gluon and ghost propagators in three-dimensional pure SU(2) gauge theory. Data have been obtained using asymmetric lattices (V = 20×60, 40×60, 8 × 64, 8 × 140, 12 × 140 and 16 × 140) for the lattice coupling β = 3.4, in the scaling region. We find that the gluon (respectively ghost) propagator is suppressed (respec. enhanced) at small momenta i...
متن کاملInfrared Propagators in MAG and Feynman gauge on the lattice
We propose to investigate infrared properties of gluon and ghost propagators related to the so-called Gribov-Zwanziger confinement scenario, originally formulated for Landau and Coulomb gauges, for other gauges as well. We present results of our investigation of SU(2) lattice gauge theory in the maximally Abelian gauge (MAG), focusing on the behavior of propagators in the off-diagonal (i.e. non...
متن کاملComparing SU ( 2 ) to SU ( 3 ) gluodynamics on large lattices
We study the SU(2) gluon and ghost propagators in Landau gauge on lattices up to a size of 112 4. A comparison with the SU(3) case is made and finite-volume effects are then investigated. We find that for a large range of momenta the SU(2) and SU(3) propagators are remarkably alike. In the low-momentum region we compare with recent results obtained in DSE studies on a 4-torus. c Copyright owned...
