Gluon propagator and confinement scenario in Coulomb gauge
A particularly simple confinement scenario [1] is available in the minimal Coulomb gauge. It attributes confinement of color to the long range of the color-Coulomb potential Vcoul(R). This quantity is the instantaneous part of the 4-4 component of the gluon propagator, Dμν(x) ≡ 〈gAμ(x) gAν(0)〉, namely D44(x, t) = Vcoul(|x|)δ(t) +P (x, t). The vacuum polarization term P (x, t) is less singular t...
متن کاملCasimir scaling hypothesis on the nonperturbative force in QCD vs . dual superconducting scenario of confinement ∗
From the SU(2) and SU(3) lattice QCD studies of the static potential between color charges in various dimensional representations, there arises the Casimir scaling hypothesis for the intermediate distance force [ 1, 2, 3]. This hypothesis tells that the ratio of forces associated with various dimensional representations of color charges, for a given color group, is determined by that of eigenva...
متن کاملDual superconductor scenario of confinement: A systematic study of Gribov copy effects.
We perform a study of the effects from maximal abelian gauge Gribov copies in the context of the dual superconductor scenario of confinement, on the basis of a novel approach for estimation of systematic uncertainties from incomplete gauge fixing. We present numerical results, in SU(2) lattice gauge theory, using the overrelaxed simulated annealing gauge fixing algorithm. We find abelian and no...
متن کاملNumerical Study of Gluon Propagator and Confinement Scenario in Minimal Coulomb Gauge
We present numerical results in SU(2) lattice gauge theory for the space-space and time-time components of the gluon propagator at equal time in the minimal Coulomb gauge. It is found that the equal-time would-be physical 3-dimensionally transverse gluon propagator Dtr(~k) vanishes at ~k = 0 when extrapolated to infinite lattice volume, whereas the instantaneous color-Coulomb potential D44(~k) ...
متن کاملLennard-Jones binary mixture in disordered matrices: exploring the mode coupling scenario at increasing confinement.
We present results of molecular dynamics simulations performed on a Lennard-Jones liquid binary mixture confined in matrices of soft spheres at increasing packing fraction. We study the dynamical properties of the liquid at a given density upon supercooling. Our aim is to test the validity of the mode coupling theory in predicting the behaviour of the glass forming liquid when it is under confi...
