Attilio Cucchieri, Daniel Zwanziger
TL;DR
This paper presents numerical lattice gauge theory results for the gluon propagator in Coulomb gauge, supporting the confinement scenario through a linearly rising color-Coulomb potential in SU(2).
Contribution
It provides new numerical evidence for the behavior of the gluon propagator and the confinement scenario in Coulomb gauge within SU(2) lattice gauge theory.
Findings
Gluon propagator data are consistent with a linearly rising potential.
Numerical results support the confinement scenario in Coulomb gauge.
Data obtained on large lattice volumes across multiple beta values.
Abstract
We present numerical results in SU(2) lattice gauge theory for the instantaneous part of the gluon propagator in Coulomb gauge D_{44, inst} = V_{coul}(R) \delta(t). Data are taken on lattice volumes 24^4 and 28^4 for 7 values of beta in the interval . The data are confronted with the confinement scenario in Coulomb gauge. They are consistent with a linearly rising color-Coulomb potential V_{coul}(R).
