The hypothesis that the QCD vacuum can be modeled as a dual superconductor is a powerful tool to describe the distribution of the color field generated by a quark-antiquark static pair and, as such, can provide useful clues for the understanding of confinement. In this work we investigate, by latticeMonte Carlo simulations of the SU(3) pure gauge theory and of (2 + 1)-flavor QCD with physical mass settings, some properties of the chromoelectric flux tube at zero temperature and their dependence on thephysical distance between the static sources. We draw some conclusions about the validity domain of thedual superconductor picture.

Abstract
The hypothesis that the QCD vacuum can be modeled as a dual superconductor is a powerful tool to describe the distribution of the color field generated by a quark-antiquark static pair and, as such, can provide useful clues for the understanding of confinement. In this work we investigate, by latticeMonte Carlo simulations of the SU(3) pure gauge theory and of (2 + 1)-flavor QCD with physical mass settings, some properties of the chromoelectric flux tube at zero temperature and their dependence on thephysical distance between the static sources. We draw some conclusions about the validity domain of thedual superconductor picture.File in questo prodotto:
