Entropic destruction of a moving heavy quarkonium [PDF]
Phys. Rev. D 94, 026007 (2016), 2015 Recently it has been shown that the peak of the quarkonium entropy at the deconfinement transition is related to the emergent entropic force which destructs the quarkonium. Using the AdS/CFT correspondence, we consider dissociation of a moving heavy quarkonium by entropic force.

QUARKONIUM AT FINITE TEMPERATURE [PDF]
, 2010 We discuss properties of heavy quarkonium states at high temperatures based on lattice QCD and potential models. We review recent progress made in lattice calculations of spatial static quark anti-quark correlators as well as quarkonium correlators in Euclidean time.

Quarkonium measurements in nucleus-nucleus collisions with ALICE [PDF]
, 2020 Heavy quarks are produced in the early stages of nucleus-nucleus collisions and can therefore provide important insight into the Quark-Gluon Plasma (QGP). Quarkonia are proposed as crucial probes to study the QGP. The extent of the medium modification for heavy-quark quarkonium production in heavy-ion collisions is measured in terms of a nuclear ...

The Quarkonium Analysis of the QGP [PDF]
EPJ Web of Conferences, 2014 Quarkonium production has been considered as a tool to study the medium formed in high energy nuclear collisions, assuming that the formation of a hot and dense environment modifies the production pattern observed in elementary collisions. The basic features measured there are the relative fractions of hidden to open heavy flavor and the relative ...

Quarkonium formation time in quark-gluon plasma [PDF]
, 2013 The quarkonium formation time in a quark-gluon plasma (QGP) is determined from the space-time correlator of heavy quark vector currents using the quarkonium in-medium mass and wave function obtained from heavy quark potentials extracted from the lattice QCD.

Nucleon-Quarkonium Elastic Scattering and the Gluon Contribution to Nucleon Spin [PDF]
Phys.Rev.Lett. 82 (1999) 4985-4987, 1999 It is shown that the amplitude for the scattering of a heavy quarkonium system from a nucleon near threshold is completely determined by the fraction of angular momentum, as well as linear momentum, carried by gluons in the nucleon. A form for the quarkonium-nucleon non-relativistic potential is derived.

Quarkonium polarization as a test of non-relativistic effective theory [PDF]
arXiv, 1997 I compare current approaches to quarkonium production with regard to what they tell us about quarkonium polarization. Predictions for $J/\psi$ polarization in hadron-hadron and photon-hadron collisions are summarized.

QUARKONIUM PRODUCTION IN HADRONIC COLLISIONS [PDF]
International Journal of Modern Physics A, 1995 We summarize the theoretical description of charmonium and bottonium production in hadronic collisions and compare it to the available data from hadron-nucleon interactions. With the parameters of the theory established by these data, we obtain predictions for quarkonium production at RHIC and LHC energies.
