摘要：The critical behavior of zero-momentum correlation functions of the energy-momentum tensor
components near the second order nite temperature transition of the (3+1)-dimensional SU(2)
gauge theory is studied. While the correlation function of the trace of the energy-momentum tensor
is shown to diverge uniformly like the specic heat as the critical temperature is approached,
the pressure-pressure correlation function remains nite. Implications relevant for the calculation
of transport coefcients, in particular the bulk viscosity, in the vicinity of a second order phase
transition are discussed.
