Gauge invariant structures and Confinement
arXiv:hep-lat/9507006 · doi:10.1016/0370-2693(95)01056-V
Abstract
By looking at cooled configurations on the lattice, we study the presence of peaks in the action density, or its electric and magnetic components, in the SU(2) gauge vacuum. The peaks are seen to be of instanton-like nature and their number variation takes care of the drop in the string tension observed when cooling. Possible explanations of this finding are analysed.
