Description
The heavy quark diffusion coefficient is encoded in the spectral
functions of the chromo-electric and the chromo-magnetic correlators that are
calculable on the lattice. We study the chromo-electric and the chromo-magnetic correlator in the deconfined phase of SU(3) gauge theory using Symanzik flow at
two temperatures 1.5Tc and 10000Tc, with Tc being the phase transition
temperature. To control the lattice discretization errors and perform
the continuum limit we use several temporal lattice extents Nt=16,20,24,28 and 34. We observe that the flow time dependence of the chromo-magnetic correlator
is quite different from chromo-electric correlator most likely due to
the anomalous dimension of the former as has been pointed out recently in
the literature.
