2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/38582A new method is proposed for determining the critical indices of the deconfinement transition in gauge theories, based on the finite-size scaling analysis of simple lattice operators, such as the plaquette. A precise determination of the critical index $ν$, in agreement with the prediction of the Svetitsky-Yaffe conjecture, is obtained for SU(3) gauge theory in (2+1)-dimension. Preliminary results for SU(2) in (3+1)-dimension are also given.poster at Lattice2001(hightemp), 3 pages, 2 figures, uses espcrc2.styHigh Energy Physics - Latticetext
