Gluon propagator and confinement scenario in Coulomb gauge
Abstract
We present numerical results in SU(2) lattice gauge theory for the instantaneous part of the gluon propagator in Coulomb gauge D44, inst = Vcoul(R) δ(t). Data are taken on lattice volumes 244 and 284 for 7 values of beta in the interval 2.2 ≤ beta ≤ 2.8. The data are confronted with the confinement scenario in Coulomb gauge. They are consistent with a linearly rising color-Coulomb potential Vcoul(R).
