  The Gribov-Zwanziger prescription applied within Yang-Mills theory is
demonstrated to be an efficient method for refining the theory's infrared
dynamics. We study the collisional energy loss experienced by a high-energetic
test parton as it traverses through the Grivov plasma at finite temperature. To
achieve this, we employ a semi-classical approach that considers the parton's
energy loss while accounting for the back-reaction induced by the polarization
effects due to its motion in the medium. The polarization tensor of the medium
is estimated within a non-perturbative resummation considering the
Gribov-Zwanziger approach. The modification of the gluon and ghost loops due to
the presence of the Gribov parameter plays a vital role in our estimation. We
observe that the non-perturbative interactions have a sizable effect on the
parton energy loss. Further, we discuss the implications of our findings in the
context of relativistic heavy-ion collisions.
