Modelling the gluon propagator

چکیده
where the subscript f denotes the finer lattice (β = 6.2 in this study) and the subscript c denotes the coarser lattice (β = 6.0). We can use this relation to study directly the scaling properties of the lattice gluon propagator by matching Talk presented by D. B. Leinweber UKQCD Collaboration the data for the two values of β. This matching can be performed by adjusting the values for the ratios RZ = Zf/Zc and Ra = af/ac until the two sets of data lie on the same curve. We have implemented this by making a linear interpolation of the logarithm of the data plotted against the logarithm of the momentum for both data sets. In this way the scaling of the momentum is accounted for by shifting the fine lattice data to the right by an amount ∆a as follows

Gribov copies, Lattice QCD and the gluon propagator
We address the problem of Gribov copies in lattice QCD. The gluon propagator is computed, in the Landau gauge, using 302 (β = 5.8) 12 configurations gauge fixed to different copies. The results of the simulation shows that: i) the effect of Gribov copies is small (less than 10%); ii) Gribov copies change essentially the lowest momenta components (q < 2.6 GeV); iii) within the statistical accura...
متن کاملModelling the quark propagator
The quark propagator is at the core of lattice hadron spectrum calculations as well as studies in other nonperturbative schemes. We investigate the quark propagator with an improved staggered action (Asqtad) and an improved gluon action, which provides good quality data down to small quark masses. This is used to construct ansätze suitable for model hadron calculations as well as adding to our ...
متن کاملCritical Coupling for Dynamical Chiral-Symmetry Breaking with an Infrared Finite Gluon Propagator
We compute the critical coupling constant for the dynamical chiralsymmetry breaking in a model of quantum chromodynamics, solving numerically the quark self-energy using infrared finite gluon propagators found as solutions of the Schwinger-Dyson equation for the gluon, and one gluon propagator determined in numerical lattice simulations. The gluon mass scale screens the force responsible for th...
متن کاملIR suppression of the Coulomb gauge gluon propagator in SU(3) Yang-Mills theory
We calculate the equal-time transverse gluon propagator in Coulomb gauge QCD using a SU(3) quenched lattice gauge simulation on large lattices, up to 11 [fm4]. We find that the equal-time gluon propagator shows scaling violation; namely, the data for different lattice spacings do not fall on top of one curve. This problem is cured by discarding data at large momenta, which suffer from discretiz...
متن کاملGluon Propagator on a Coarse Anisotropic Lattice
We calculated the SU(2) gluon propagator in Landau gauge on an anisotropic coarse lattice with the improved action. The standard and the improved scheme are used to fix the gauge in this work. Even on the coarse lattice the lattice gluon propagator can be well described by a function of the continuous momentum. The effect of the improved gauge fixing scheme is found not to be apparent. Based on...
متن کاملGauge and Lorentz Covariant Quark Propagator in an Arbitrary Gluon Field
The quark propagator in presence of an arbitrary gluon field is calculated gauge and Lorentz covariantly order by order in terms of powers of gluon field and its derivatives. The result is independent of path connecting ends of propagator and leading order result coincides with the exact propagator in the trivial case of vanishing gluon field.
