摘要：The mass spectrum of the 3d 3-state Potts model is considered in the broken phase (a) near the
second order Ising critical point in the temperature-magnetic field plane and (b) near the weakly
first order transition point at zero magnetic field. In the case (a), the mass spectrum is compared
with the prediction from universality of mass ratios in the 3d Ising class; in the case (b) a mass
ratio is determined to be compared with the corresponding one in the spectrum of screening
masses of the (3+1)d SU(3) pure gauge theory at finite temperature in the deconfined phase near
the transition.
