Gross-Witten point and deconfinement

摘要

Following Aharony et al., we analyze the deconfining phase transition in a SU(infinity) gauge theory in mean field approximation. The Gross-Witten model emerges as an "ultra"-critical point for deconfinement: while thermodynamically of first order, masses vanish, asymmetrically, at the transition. Potentials for N = 3 are also shown.
