Description
For quark-antiquark separation $r \ll 1/T$, the interaction of a
quarkonium with a quark-gluon plasma medium can be approximated by a
dipole interaction with a color electric field. The evolution and decay
of the quarkonia in the plasma can then be calculated from transport
coefficients calculated from the thermal correlator of color electric
fields connected by an adjoint Wilson line.
We present a lattice calculation of these correlators in a
gluon plasma. We will study the structure of the correlator and the spectral
function, and extract the relevant transport coefficient.
We will also compare the correlator with the closely related one used for
the study of heavy quark diffusion coefficient.
