Correlation length and susceptibility near the SU(2) deconfining phase transition

Additional results from a Monte Carlo simulation of SU(2) pure gauge theory near the finite-temperature, deconfining phase transition are presented. The new data are from a 15³×{}4 lattice at a value of 4/g²=2.285 that is just inside the confinement phase. The Wilson line-line correlation function has a correlation length of 6.25 lattice units. This is consistent with a growth and divergence according to the critical exponent of the three-dimensional Ising model. The susceptibility shows a rapid and apparently divergent growth. For this quantity, the data favor an exponent that is a little smaller than that of the Ising model.
