摘要：We determine from Polyakov loop correlators the screening masses in the deconned phase of
the (3+1)d SU(3) pure gauge theory at nite temperature near the transition, for two different
channels of angular momentum and parity. Their ratio is compared with that of the massive
excitations with the same quantum numbers in the 3d 3-state Potts model in the broken phase
near the transition point at zero magnetic eld. Moreover we study the inverse decay length of
the correlation between the real parts and between the imaginary parts of the Polyakov loop and
compare the results with expectations from perturbation theory and mean-eld Polyakov loop
models.
