We determine by numerical simulations on a lattice the gauge–invariant two–point correlation function of the gauge field strengths in the QCD vacuum, down to a distance of 0.1 fm.
We analyze the properties of a class of improved lattice topological charge density operators, constructed by a smearing-like procedure. By optimizing the choice of the parameters introduced in their… (More)
On the dependence of the gauge–invariant field–strength correlators in QCD on the shape of the Schwinger string * A. Abstract We study, by numerical simulations on a lattice, the dependence of the… (More)
It is shown that SU(N) gauge theory coupled to adjoint Higgs can be explicitly re-written in terms of SU(N) gauge invariant dynamical variables with local physical interactions. The resultant theory… (More)
where Gμρ = gT Gμρ is the field–stength tensor and S = S(x, 0) is the Schwinger phase operator needed to parallel–transport the tensor Gνσ(0) to the point x. These correlators govern the effect of… (More)
The abelian projection in SU(N) gauge theories is discussed in detail, as well as the construction of a disorder parameter to study dual superconductivity as a mechanism for color confinement. If the… (More)
Dual superconductivity in the confining phase of gauge theories is discussed in terms of a disorder parameter which vanishes in normal phase and is different from zero in the superconducting phase.
We study by numerical simulations on a lattice the behaviour of the gauge–invariant two– point correlation functions of the gauge–field strengths across the deconfinement phase transition, both for… (More)
