FAU-TP3-02/29 KUGO–OJIMA CONFINEMENT CRITERION, ZWANZIGER–GRIBOV HORIZON CONDITION, AND INFRARED CRITICAL EXPONENTS IN

by Landau Gauge Qcd, R. Alkofer, C. S. Fischer, L. Von Smekal , 2003
"... The Kugo–Ojima confinement criterion and its relation to the infrared behaviour of the gluon and ghost propagators in Landau gauge QCD are reviewed. The realization of this confinement criterion (which in Landau gauge relates to Zwanziger’s horizon condition) results from quite general properties of ..."

The nilpotent BRST symmetry for the Gribov-Zwanziger theory

by Kei-ichi Kondo , 905
"... We have obtained the nilpotent BRST symmetry of Yang-Mills theory restricted to the Gribov region. In fact, we give a modified BRST transformation that leaves the Gribov-Zwanziger action invariant and obeys the nilpotency, although the usual BRST symmetry is broken due to the non-vanishing Gribov pa ..."

Gribov’s horizon and the ghost dressing function

by Ph. Boucaud A, J. P. Leroy A, A. Le Yaouanc A, J. Micheli A, O. Pène A, J. Rodríguez-quintero B, Dpto Física Aplicada, Fac Ciencias Experimentales , 909
"... We study a relation recently derived by K. Kondo at zero momentum between the Zwanziger’s horizon function, the ghost dressing function and Kugo’s functions u and w. We agree with this result as far as bare quantities are considered. However, assuming the validity of the horizon gap equation, we arg ..."

More (Thoughts on) Gribov Copies

by Pierre van Baal - NUCL. PHYS. B , 1992
"... Inspired by an unambiguous observation of Gribov copies on the lattice an old continuum example due to Henyey is reanalysed in terms of bifurcations at the Gribov horizon. This gives yet another proof that there are in general Gribov copies within the horizon. Using results by Semenov-Tyan-Shansk ..."

-Tyan-Shanskii, Franke, Dell'Antonio and Zwanziger on a possible fundamental modular domain we argue that its boundary has both Gribov copies and points that coincide with the Gribov horizon.

Features of the Refined Gribov-Zwanziger theory: propagators, BRST soft symmetry breaking and glueball masses

by Silvio P. Sorella, David Dudal, Marcelo S. Guimarães, Nele Vandersickel, Cientista Do Nosso Estado
"... The present work discusses an approach to access the physical spectrum of the Yang-Mills theory quantized in the Landau gauge. By using recent lattice data on the gluon propagator, it is possible to study the two-point functions of gauge invariant composite operators, from which masses of glueballs ..."

can be extracted. It turns out that the momentum dependence of the gluon propagator is very well reproduced by the corresponding tree-level gluon propagator obtained from the Refined Gribov-Zwanziger theory, which takes into account the presence of the Gribov horizon as well as the effect

Decoupling and scaling solutions in Yang-Mills theory with the Gribov horizon

by Kei-ichi Kondo , 909
"... We propose a trick which enables one to incorporate the Gribov horizon into the Schwinger-Dyson equation in Landau and Coulomb gauge Yang-Mills theory, using the Gribov-Zwanziger framework with the horizon term. We find a family of solutions parameterized by one-parameter wR(0) which was overlooked ..."

LTH-702 One loop gluon form factor and freezing of αs in the Gribov-Zwanziger QCD Lagrangian

by L Bx , 2006
"... Abstract. We use the Gribov-Zwanziger Lagrangian in QCD to evaluate the one loop correction to the gluon propagator as a function of the Gribov volume and verify that the propagator vanishes in the infrared limit. Using the corresponding correction to the Faddeev-Popov ghost propagator we construct ..."
