The gluon condensate from gauge invariant vortex vacuum texture
A revival of the vortex picture of quark confinement arose with the construction of the p-vortices which are defined after adopting the so-called center gauge 1 by projecting the gauge fixed link variables onto center elements . In this case, it was observed that the vortices are sensible degrees of freedom in the continuum limit : the (area) density of the p-vortices as well as their binary in...
متن کاملGauge invariant vortex vacuum textures and the gluon condensate
In SU(2) lattice gauge theory, a new self-restricted cooling procedure is developed which removes the SU(2)/Z2 coset fields from the lattice configurations and thus reveals the the Z2 vortex vacuum texture. The emerging gauge invariant vortex vacuum structure amounts to the full string tension. The action density of the vortex texture extrapolates to the continuum limit, and, hence, gives rise ...
متن کاملGauge-invariant gluon mass, infrared Abelian dominance and stability of magnetic vacuum
We give an argument for deriving analytically the infrared “Abelian” dominance in a gauge invariant way for the Wilson loop average in SU(2) Yang– Mills theory. In other words, we propose a possible mechanism for realizing the dynamical Abelian projection in the SU(2) gauge-invariant manner without breaking color symmetry. This supports validity of the dual superconductivity picture for quark c...
متن کاملGauge invariant Z ( 2 ) vortex vacuum textures and the SU ( 2 ) gluon condensate
For SU(2) lattice gauge theory, a new SO(3) cooling procedure is proposed which removes the SU(2)/Z(2) coset fields from the lattice configurations and reveals a Z(2) vortex vacuum texture different from the P–vortex content obtained in the maximal center gauge. Cooling can be restricted in a renormalization group invariant way by a parameter controlling the remaining SO(3) action density. A ga...
