bibo_abstract:
- Recently, a finite-temperature real-time static potential has been introduced
via a Schrodinger-type equation satisfied by a certain heavy quarkonium Green's
function. Furthermore, it has been pointed out that it possesses an imaginary
part, which induces a finite width for the tip of the quarkonium peak in the thermal
dilepton production rate. The imaginary part originates from Landau-damping of
low-frequency gauge fields, which are essentially classical due to their high
occupation number. Here we show how the imaginary part can be measured with classical
lattice gauge theory simulations, accounting non-perturbatively for the infrared
sector of finite-temperature field theory. We demons trate that a non-vanishing
imaginary part indeed exists non-perturbatively; and that its value agrees semi-quantitatively
with that predicted by Hard Loop resummed perturbation theory.@eng
