Spectral representation of lattice gluon and ghost propagators at zero temperature
David Dudal, Orlando Oliveira, Martin Roelfs +1
We consider the analytic continuation of Euclidean propagator data obtained from 4D simulations to Minkowski space. In order to perform this continuation, the common approach is to…
Ghost Sector in Minimal Linear Covariant Gauge
Attilio Cucchieri, David Dudal, Tereza Mendes +3
We discuss possible definitions of the Faddeev-Popov matrix for the minimal linear covariant gauge on the lattice and present preliminary results for the ghost propagator.
Lattice Computation of the Ghost Propagator in Linear Covariant Gauges
Attilio Cucchieri, David Dudal, Tereza Mendes +3
We discuss the subtleties concerning the lattice computation of the ghost propagator in linear covariant gauges, and present preliminary numerical results.
Lattice Landau gauge gluon propagator at finite temperature: non-zero Matsubara frequencies and spectral densities
Paulo J. Silva, Orlando Oliveira, David Dudal +1
The lattice Landau gauge gluon propagator at finite temperature is computed including the non-zero Matsubara frequencies. Furthermore, the Källén-Lehmann representation is inverted…
