  Gribov-Zwanziger prescription in Yang-Mills theory improves the infrared
dynamics. In this work, we study the static potential of a heavy
quark-antiquark pair with the HTL resummed perturbation method within the
Gribov-Zwanziger approach at finite temperature. The real and imaginary parts
of the heavy quark complex potential are obtained from the one-loop effective
static gluon propagator. The one-loop effective gluon propagator is obtained by
calculating the one-loop gluon self-energies containing the quark, gluon, and
ghost loop. The gluon and ghost loops are modified in the presence of the
Gribov parameter. We also calculate the decay width from the imaginary part of
the potential. We also discuss the medium effect of heavy quark potential with
the localized action via auxiliary fields.
