Modelling the gluon propagator
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 ratio...
متن کاملOn the Infrared Gluon Propagator
The infrared limit of the lattice Landau gauge gluon propagator is studied. We show that the lattice data is compatible with the pure power law (q2)2κ solution of the Dyson-Schwinger equations. Using various lattice volumes, the infinite volume limit for the exponent κ is measured. The value obtained, κ ∼ 0.52, supports a vanishing zero momentum gluon propagator.
متن کاملThe Gluon Propagator at High Temperature
We study the gluon propagator in Landau gauge in the deconfined phase of SU(2) gauge theory. From the long-distance behaviour of correlation functions of temporal and spatial components of the gauge fields we extract electric (m e) and magnetic (m m) screening masses. For temperatures larger than twice T c we find no additional temperature dependence in m e (T)/T , while m m (T)/T drops with in...
متن کاملThe IR gluon propagator from lattice QCD
The gluon propagator is computed in large asymmetric lattices, accessing momenta around 100 MeV and smaller. Our study tries to check the compatibility of the recent solutions of the gluonghost Dyson-Schwinger equations with lattice results. In particular the exponent κ , which characterizes the solutions for the infrared, is measured. Results favours a vanishing zero momentum gluon propagator....
متن کاملThe Gluon Propagator on a Large Volume
We present the results of a high statistics lattice study of the gluon propagator, in the Landau gauge, at β = 6.0. As suggested by previous studies, we find that, in momentum space, the propagator is well described by the expression G(k 2) = M 2 + Z · k 2 (k 2 /Λ 2) η −1. By comparing G(k 2) on different volumes, we obtain a precise determination of the exponent η = 0.532(12), and verify that ...
