Insights into phase transition behavior in SU(2) gauge theory

Abstract

We study the spectrum of screening masses in the deconfined phase of (3+1)D SU(2) pure gauge theory near criticality and compare it with the spectrum of bound states in the broken symmetry phase of the 3D Ising model, which is related to the gauge theory by universality.
