Quarkonium semiclassical transport in quark-gluon plasma: factorization and quantum correction [PDF]
Journal of High Energy Physics, 2021 We study quarkonium transport in the quark-gluon plasma by using the potential nonrelativistic QCD (pNRQCD) effective field theory and the framework of open quantum systems. We argue that the coupling between quarkonium and the thermal bath is weak using

Real time quarkonium transport coefficients in open quantum systems from Euclidean QCD [PDF]
Physical Review D, 2023 Recent open quantum system studies showed that quarkonium time evolution inside the quark-gluon plasma is determined by transport coefficients that are defined in terms of a gauge invariant correlator of two chromoelectric field operators connected by an

The complex heavy quarkonium potential with the Gribov–Zwanziger action [PDF]
The European Physical Journal C, 2023 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 ...
