Abstract

We study the behavior of the spatial and temporal 't Hooft loop at zero and finite temperature in the 4D SU(2) Yang-Mills theory, using a new numerical method. In the deconfined phase $T > T_{c}$ , the spatial 't Hooft loop exhibits a dual string tension, which vanishes at $T_{c}$ with a 3D Ising-like critical exponent.
