Description
Non-perturbative resummation at finite temperature via the Gribov gluon propagator was proposed by D. Zwanziger in 2005 [1]. Later, in 2013, it was used by K. Fukushima and N. Su [2] to study gluon thermodynamics. In 2015, N. Su and T. Tywoniuk showed that a novel massless excitation is ascribable to the magnetic scale in quark dispersion relations.
We recently used the non-perturbative resummation via the Gribov gluon propagator to calculate various quantities relevant to hot and dense nuclear matter. We have studied share and bulk viscosities [4], heavy quark diffusion coefficient[5], meson screening mass[6], heavy quarkonium potential[7], et. al. In all the cases, we get an improvement over the perturbative result near the transition temperature. In this talk, I will discuss the recent findings we obtained using the non-perturbative resummation.
