A model for QCD ground state with magnetic disorder
arXiv:1003.1901 · doi:10.1103/PhysRevD.81.094007
Abstract
We explore an ansatz for the QCD vacuum in the Coulomb gauge that describes gauge field fluctuations in presence of a weakly interacting gas of abelian monopoles. Such magnetic disorder leads to long-range correlations which are manifested through the area law for the Wilson loop. In particular we focus on the role of the residual monopole-monopole interactions in providing the mechanism for suppression of the gluon propagator at low-momenta which also leads to low momentum enhancement in the ghost propagator.
