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.
