Numerical results for the line-line correlation length near the SU(2) deconfining phase transition

Results from a Monte Carlo simulation of SU(2) pure gauge theory near the finite-temperature, deconfining phase transition are presented. The lattice is ${11}^3$×4, and the data were collected at values of 4/$g^2$=2.200, 2.225, 2.250, and 2.275 that approach the transition from the low-temperature, confinement side. The Wilson line-line correlation function was measured and the correlation length extracted. The data are consistent with a correlation length that is diverging according to the critical exponent of the three-dimensional Ising model.
