Mass estimates of the SU(2) glueball from spectral methods
David Dudal, Orlando Oliveira, Martin Roelfs
The estimation of the Källén-Lehmann spectral density from gauge invariant lattice QCD two point correlation functions is proposed, and explored via an inversion strategy based on…
Källén-Lehmann Spectral Representation of the Scalar SU(2) Glueball
David Dudal, Orlando Oliveira, Martin Roelfs
The estimation of the Källén-Lehmann spectral density from gauge invariant lattice QCD two point correlation functions is proposed, and explored via an appropriate inversion method…
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.
Faddeev-Popov Matrix in Linear Covariant Gauge: First Results
Attilio Cucchieri, David Dudal, Tereza Mendes +3
We discuss a possible definition of the Faddeev-Popov matrix for the minimal linear covariant gauge on the lattice and present first results for the ghost propagator. We consider Y…
