Quantum Chromodynamics: the Gluon Propagator Corresponding to Linear Confinement
The exact nonperturbative confining solutions of the SU(3)-Yang-Mills equations recently obtained by author in Minkowski spacetime with the help of the black hole theory techniques are analysed and on the basis of them the gluon propagator corresponding to linear confinement at large distances (small momenta) is constructed in a nonperturbative way. At small distances (large momenta) the result...
متن کاملNonperturbative propagators in quantum chromodynamics.
Leading nonperturbative corrections to the quark and gluon propagators are derived following the assumption that the nonperturbative QCD vacuum can be described in terms of non-vanishing vacuum expectation values for the composite operators [T&I and [GEY]. Th e nonperturbative quark propagator can be described in terms of a running quark mass and a running normalization function. These quantiti...
متن کاملManifestation of Confinement in the Gluon propagator
Understanding the physics of hadrons in particular the mechanism of confinement and spontaneous breaking of chiral symmetry requires a non-perturbative treatment of QCD, which is the theory of strong interaction. To date the only rigorous non-perturbative approach to QCD are the Monte Carlo lattice calculations. Despite recent progress by improved lattice algorithm and the increase in computer ...
متن کاملSoft Gluon Effects in Perturbative Quantum Chromodynamics*
The problem of the inclusion of sub-leading logarithms to all orders of the perturbative expansion is considered and solved in the case of multiple soft gluon emission. The evaluation of the entire set of the _ sub-dominant contributions is performed in a consistent way at two loop level in the impact parameter space for the effective quark form factor. The effect of the inclusion of the single...
متن کاملGluon 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...
