UNIVERSAL AMPLITUDE RATIOS AND FUNCTIONS FOR THE SU(2) FINITE-TEMPERATURE PHASE-TRANSITION

Universal functions and amplitude ratios associated with the classes of second-order phase transitions are used as additional tests of the prediction that the pure glue, SU(2), finite-temperature, deconfining phase transition is in the universality class of the three-dimensional Ising model. From published gauge theory Monte Carlo data, we extract information on these functions and ratios and compare them with theory and Ising-model numerical results. The qualitative and rough quantitative agreement are encouraging. However, there are some definite quantitative discrepancies.
