Investigations on the Coulomb flux tube

SU(N) Coulomb gauge Lattice QCD provides an effective way to probe aspects of quark confinement. It allows investigation of the effect of the instantaneous color Coulomb interaction on the energy density profile between static quark-antiquark pairs. Recent works have computed the Coulomb flux tube profile and compared it to the Wilsonian flux tube to distinguish between collimated and dipole-like behavior. However, these results were not definitive. We will present our attempts to continue these calculations on larger lattice volumes. Due to the instantaneous nature of the Coulomb interaction, Coulomb gauge observables are defined in the limit where their time extent vanishes. We also discuss the time evolution of the coulomb flux tube as well as extrapolation of the limit β→∞ on anisotropic lattices to gain insight into this T→0 limit.
