Aspects of confinement within non-Abelian gauge theories
Résumé
These lectures cover two aspects: first, irrespectively of the particular approach followed to tackle the QCD phase diagram, we introduce some tools that help discussing the confinement/deconfinement transition in the continuum; second, within one particular continuum approach, based on the Curci-Ferrari model, we illustrate the use of these various notions in order the describe to the confinement/deconfinement transition.
