2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/39047We survey recent lattice results on QCD topological properties. The behaviour of the topological susceptibility at the deconfining phase transition has been determined. This advance has been made possible by an i) an improvement of the topological charge operator and ii) a non-perturbative determination of renormalizations.4 pages, 9 postscript figures, uses stwol.sty file included.
