A test of the Kugo-Ojima confinement criterion by lattice Landau gauge QCD simulations
نویسنده
چکیده
The first test of the Kugo-Ojima colour confinement criterion by the lattice Landau gauge QCD simulation is performed. The parameter u which is expected to be −1δ b in the continuum theory was found to be −0.7δ b in the strong coupling region. The data is analysed in connection with the theory of Zwanziger. In the weak coupling region, the expectation value of the horizon function is negative or consistent to 0.

Color Confinement in Lattice Landau Gauge
The problem of color confinement in lattice Landau gauge QCD is briefly reviewed in the light of Kugo-Ojima criterion and Gribov-Zwanziger theory. The infrared properties of the Landau gauge QCD is studied by the measurement of the gluon propagator, ghost propagator, Kugo-Ojima parameter and the running coupling via β = 6.0, 16, 24, 32 and β = 6.4, 32, 48 lattice simulation. The data are analyz...
متن کاملColour Confinement in the Lattice Landau Gauge Qcd Simulation
Two decades ago, Gribov pointed out a possible mechanism of colour confinement in Coulomb gauge or Landau gauge QCD via infrared divergence of the Faddeev-Popov ghost propagator. At nearly the same time, Kugo and Ojima proposed a criterion for the absence of coloured massless asymptoptic states in Landau gauge QCD using the BRST symmetry. We study the confinement signal in the gluon propagator,...
متن کاملKugo – 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 کاملThe Infrared Behavior of QCD Propagators in Landau Gauge
Some features of the solutions to the truncated Dyson-Schwinger equations(DSEs) for the propagators of QCD in Landau gauge are summarized. In particular, the Kugo-Ojima confinement criterion is realized, and positivity of transverse gluons is manifestly violated in these solutions. In Landau gauge, the gluon-ghost vertex function offers a convenient possibility to define a nonperturbative runni...
متن کاملNumerical Tests of the Kugo-ojima Color Confinement Criterion
The Kugo-Ojima color confinement criterion, which is based on the BRST symmetry of QCD is numerically tested by the lattice Landau gauge simulation. We first discuss the BRST symmetry on the lattice and the Gribov copy problem. The horizon function defined by Zwanziger based on the U -linear definition of the gauge field and that based on logU are compared. The parameter u which is expected to ...
