Abstract: (Elsevier)
The deconfinement transition in SU (2) gauge theory and the magnetization transition in the Ising model belong to the same universality class. The critical behaviour of the Ising model can be characterized either as spontaneous breaking of the Z 2 symmetry of spin states or as percolation of appropriately defined spin clusters. We show that deconfinement in SU (2) gauge theory can be specified as percolation of Polyakov loop clusters with Fortuin-Kasteleyn bond weights, leading to the same (Onsager) critical exponents as the conventional order-disorder description based on the Polykov loop expectation value.
