The analytic structure of the QCD propagators, confinement, and deconfinement
Giorgio Comitini
We present the first complete calculation of the analytic structure of the zero-spatial-momentum finite-temperature Landau-gauge gluon propagator carried out at one loop by a massi…
Nonperturbative Higgs-Schwinger mechanism at the origin of the gluon mass and color confinement
Giorgio Comitini
Evidence from lattice and continuum studies supports the existence of a fully nonperturbative Higgs mechanism generating mass for gluons in linear covariant gauges. The broken char…
One-loop analytic structure of the deep-infrared Landau-gauge gluon propagator at finite temperature
Giorgio Comitini
With the aim of looking for signatures of deconfinement, the poles and the spectral function of the Landau-gauge gluon propagator are investigated at one loop, vanishing spatial mo…
Topological Susceptibility in the Superconductive Phases of Quantum Chromodynamics: a Dyson-Schwinger Perspective
Fabrizio Murgana, Giorgio Comitini, Marco Ruggieri
We test non-perturbative gluon propagators recently studied in the literature, by computing the topological susceptibility, , of the superconductive phases of Quantum Chromodyna…
QCD phase diagram from the gluon propagator at finite temperature and density
Giorgio Comitini, Fabio Siringo
The screened massive expansion of full QCD is used in conjunction with a model for infrared quark masses to compute the Landau-gauge gluon propagator at finite temperature and bary…
Dynamically massive linear covariant gauges: setup and first results
Giorgio Comitini, Tim De Meerleer, David Dudal +1
We discuss the possibility to obtain a massive Landau gauge, based on the local composite operator (LCO) effective action framework combined with the Zimmerman reduction of couplin…
