The Landau gauge lattice ghost propagator in stochastic perturbation theory
We present oneand two-loop results for the ghost propagator in Landau gauge calculated in Numerical Stochastic Perturbation Theory (NSPT). The one-loop results are compared with available standard Lattice Perturbation Theory in the infinite-volume limit. We discuss in detail how to perform the different necessary limits in the NSPT approach and discuss a recipe to treat logarithmic terms by int...
متن کاملColor 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 کاملThe lattice ghost propagator in Landau gauge up to three loops using Numerical Stochastic Perturbation Theory
We complete our high-accuracy studies of the lattice ghost propagator in Landau gauge in Numerical Stochastic Perturbation Theory up to three loops. We present a systematic strategy which allows to extract with sufficient precision the non-logarithmic parts of logarithmically divergent quantities as a function of the propagator momentum squared in the infinite-volume and a → 0 limits. We find a...
متن کاملQuantisation and Gauge Invariance
Recent developments concerning canonical quantisation and gauge invariant quantum mechanical systems and quantum field theories are briefly discussed. On the one hand, it is shown how diffeomorphic covariant representations of the Heisenberg algebra over curved manifolds of non trivial topology involve topology classes of flat U(1) bundles. On the other hand, through some examples, the recently...
متن کاملInfrared features of unquenched Lattice Landau Gauge QCD
The running coupling and the Kugo-Ojima parameter of unquenched lattice Landau gauge are simulated and compared with the continuum theory. Although the running coupling measured by the ghost and gluon dressing function is infrared suppressed, the running coupling has the maximum of α0 ∼ 2−2.5 at around q = 0.5GeV irrespective of the fermion actions (Wilson fermions and Kogut-Susskind(KS) fermio...
