DOI: 10.1103/physrevd.100.014008
Abstract: We consider the quarkonium diffusion, dissociation and recombination inside a quark-gluon plasma. We compute scattering amplitudes in potential nonrelativistic QCD for relevant processes. These processes include the gluon absorption/emission at the order $gr$, inelastic scattering… read more here.

DOI: 10.1103/physrevd.96.034031
Abstract: The real-time dissociation of the heavy quarkonium in a strongly coupled boost-invariant non-Abelian plasma relaxing towards equilibrium is analyzed in a holographic framework. The effects driving the plasma out of equilibrium are described by boundary… read more here.

DOI: 10.1103/physrevd.97.016009
Abstract: We compute the decay rates for the processes $Z\to V+\gamma$, where $Z$ is the $Z$ boson, $\gamma$ is the photon, and $V$ is one of the vector quarkonia $J/\psi$ or $\Upsilon(nS)$, with $n=1$, $2$, or… read more here.

DOI: 10.3390/universe5050117
Abstract: We report on recent theory progress in understanding the production of heavy quarkonium in heavy-ion collisions based on the in-medium heavy-quark potential extracted from lattice QCD simulations. On the one hand, the proper in-medium potential… read more here.
