Heavy-flavour and quarkonium production in the LHC era: from proton-proton to heavy-ion collisions [PDF]

Eur Phys J C Part Fields, 2015
This report reviews the study of open heavy-flavour and quarkonium production in high-energy hadronic collisions, as tools to investigate fundamental aspects of Quantum Chromodynamics, from the proton and nucleus structure at high energy to deconfinement

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

Heavy Quarkonium States With Baryonic Chemical Potential [PDF]

Advances in High Energy Physics
In this work, we have studied the dissociation behavior of 1S and 2S states of quarkonium using quasiparticle approach where the Debye mass depends on baryonic chemical potential.

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.

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.

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 ...

Quarkonium correlators at finite temperature and potential models [PDF]

, 2007
We discuss the calculations of quarkonium spectral functions in potential models and their implications for the interpretation of the lattice data on quarkonium correlators. In particular, we find that melting of different quarkonium states does not lead
