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

Nonequilibrium evolution of quarkonium in medium [PDF]
EPJ Web of Conferences, 2022 We review recent progress in open quantum system approach to the description of quarkonium in the quark-gluon plasma. A particular emphasis is put on the Lindblad equations for quarkonium and its numerical simulations.

Two-loop integrals for CP-even heavy quarkonium production and decays: elliptic sectors
Journal of High Energy Physics, 2018 By employing the differential equations, we compute analytically the elliptic sectors of two-loop master integrals appearing in the NNLO QCD corrections to CP-even\ heavy quarkonium exclusive production and decays, which turns out to be the last and ...

Entropic Destruction of Heavy Quarkonium from a Deformed AdS5 Model [PDF]
Advances in High Energy Physics, 2017 We study the destruction of heavy quarkonium due to the entropic force in a deformed AdS5 model. The effects of the deformation parameter on the interdistance and the entropic force are investigated.

Suppression of quarkonium production in heavy-ion collisions at RHIC and LHC [PDF]
, 2001 A model for the production of quarkonium states in the midrapidity region at RHIC and LHC energy range is presented which explores well understood properties of QCD only. An increase of the quarkonium hadronisation time with the initial energy leads to a

The dipole picture and the non-relativistic expansion [PDF]
SciPost Physics Proceedings, 2022 We study exclusive quarkonium production in the dipole picture at next-to-leading order (NLO) accuracy, using the non-relativistic expansion for the quarkonium wavefunction.
