Masses and Thermodynamic Properties of a Quarkonium System
Canadian journal of physics (Print), 2021 Hulthen plus Hellmann potentials are adopted as the quark-antiquark interaction potential for studying the thermodynamic properties and the mass spectra of heavy mesons.

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 ...

Quarkonium Production in the QGP [PDF]
Universe, 2019 We report on recent theory progress in understanding the production of heavy quarkonium in heavy-ion collisions based on the in-medium heavy-quark potential extracted from lattice QCD simulations. On the one hand, the proper in-medium potential allows us to study the spectral properties of heavy quarkonium in thermal equilibrium, from which we estimate

Scalar quarkonium masses [PDF]
Nuclear Physics B - Proceedings Supplements, 1997 We evaluate the valence approximation to the mass of scalar quarkonium for a range of different parameters. Our results strongly suggest that the infinite volume continuum limit of the mass of $s\overline{s}$ scalar quarkonium lies well below the mass of $f_J(1710)$.

Spin Splitting Spectroscopy of Heavy Quark and Antiquarks Systems
Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020 Phenomenological potentials describe the quarkonium systems like cc¯,bb,¯ and b¯c where they give a good accuracy for the mass spectra. In the present work, we extend one of our previous works in the central case by adding spin‐dependent terms to allow for relativistic corrections.

Nonequilibrium evolution of quarkonium in medium [PDF]
EPJ Web of Conferences, 2021 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.

Hidden-charm and bottom tetra- and pentaquarks with strangeness in the hadro-quarkonium and compact tetraquark models [PDF]
Journal of High Energy Physics, 2020 In two recent papers, we used the hadro-quarkonium model to study the properties of hidden-charm and bottom tetraquarks and pentaquarks. Here, we extend the previous results and calculate the masses of heavy-quarkonium-kaon/hyperon systems.

Quarkonium semiclassical transport in quark-gluon plasma: factorization and quantum correction [PDF]
Journal of High Energy Physics, 2020 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
