Quarkonium Suppression [PDF]

Pramana 60:829-840,2003, 2002
I discuss quarkonium suppression in equilibriated strongly interacting matter. After a brief review of basic features of quarkonium production I discuss the application of recent lattice data on the heavy quark potential to the problem of quarkonium dissociation as well as the problem of direct lattice determination of quarkonium properties in finite ...

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

Eur Phys J C Part Fields, 2016
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

The Scalar Quarkonium Spectrum and Quarkonium-Glueball Mixing [PDF]

Nucl.Phys.Proc.Suppl. 63 (1998) 194-196, 1998
We evaluate the valence approximation to the mass of scalar quarkonium and to the mixing energy between scalar quarkonium and the lightest scalar glueball for a range of different lattice sizes and quark masses. Our results support the identification of $f_0(1710)$ as the lightest scalar glueball.

Associated-quarkonium production [PDF]

PoS DIS2014 (2014) 151, 2014
We discuss the growing interest to measure associated-quarkonium production in a number of channels at the LHC. Whereas back-to-back production of quarkonium + isolated photon provides a unique way to extract gluon TMDs, observables such as quarkonium + W/Z can be of great help to better understand the quarkonium production mechanism as well as to shed

Entropic destruction of heavy quarkonium in a rotating hot and dense medium from holography [PDF]

Chinese Physics C, High Energy Physics & Nuclear Physics, 2022
Previous studies have indicated that the peak of the quarkonium entropy at the deconfinement transition can be related to the entropic force which would induce the dissociation of heavy quarkonium. In this paper, we study the entropic force in a rotating hot and dense medium using AdS/CFT correspondence.

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.

Breakdown of QCD factorization for P-wave quarkonium production at low transverse momentum [PDF]

Physics Letters B, 2014
Quarkonium production at low transverse momentum in hadron collisions can be used to extract Transverse-Momentum-Dependent (TMD) gluon distribution functions, if TMD factorization holds there.

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.
