چکیده
The refined Gribov-Zwanziger (RGZ) action in the Landau gauge accounts for existence of infinitesimal Gribov copies as well dynamical formation condensates infrared Euclidean Yang-Mills theories. We couple scalar fields to RGZ and compute one-loop propagator adjoint representation group. compare our findings with existing lattice data. fate Becchi-Rouet-Stora-Tyutin symmetry this model is discussed, we provide a comparison previous proposal nonminimal coupling between matter action. find good agreement data values mass parameters that fit gluon lattice. This suggests nonperturbative information carried by framework provides suitable mechanism reproduce behavior correlation functions colored infrared.

Kugo – Ojima Confinement Criterion , Zwanziger – Gribov Horizon Condition , and Infrared Critical Exponents in Landau Gauge Qcd
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 ghost Dyson– Schwinger equation. The numerical solutions for the gluon and ghost propagators...
متن کاملLandau gauge within the Gribov horizon.
We consider a model which effectively restricts the functional integral of Yang–Mills theories to the fundamental modular region. Using algebraic arguments, we prove that this theory has the same divergences as ordinary Yang Mills theory in the Landau gauge and that it is unitary. The restriction of the functional integral is interpreted as a kind of spontaneous breakdown of the BRS symmetry.
متن کاملThe nilpotent BRST symmetry for the Gribov-Zwanziger theory
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 parameter representing the presence of the Gribov horizon in the configuration space of the Yang-Mi...
متن کاملGravity Coupled to Gauge Fields
Some exact static solutions for Einstein gravity in 2 + 1 dimensions coupled to abelian gauge field are discussed, where the invariant interval is of the form: ds = N(r)dt − dr − C(r)dθ. Some of these solutions are threedimensional analogs of the Schwarzschild black holes. The metrics in the regions inside and outside the horison are connected by the changing of the Planck mass sign. 1 On leave...
متن کاملStrongly coupled chameleon fields: new horizons in scalar field theory.
We show that, as a result of nonlinear self-interactions, scalar field theories that couple to matter much more strongly than gravity are not only viable but could well be detected by a number of future experiments provided that they are properly designed to do so.
