Quarkonium semiclassical transport in quark-gluon plasma: factorization and quantum correction

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

Quarkonium production and polarization: where do we stand? [PDF]

EPJ Web of Conferences, 2022
We review the current status of heavy quarkonium production phenomenology based on nonrelativistic effective field theories, focusing on spintriplet S -wave states such as J/ψ, ψ(2S ), and ϒ.

HEAVY QUARKONIUM [PDF]

Lepton and Photon Interactions at High Energies, 2004
I review heavy quarkonium physics in view of recent experimental results. In particular, I discuss new results on spin singlet states, photon and hadronic transitions, D–states and discovery of the yet unexplained narrow X(3872) state.

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 $f_J(1710)$.

Charmonium and exotics from lattice QCD [PDF]

EPJ Web of Conferences, 2019
We review selected lattice results on the charmonium spectrum and first attempts to search for the existence of exotic states. The hadro-quarkonium model was proposed to interpret some of the exotic states as a quarkonium core inside a hadron. We present

Quarkonium production in Pb-Pb collisions at √SNN = 5.02 TeV with ALICE

EPJ Web of Conferences, 2018
Ultra-relativistic heavy-ion collisions at the Large Hadron Collider provide a unique opportunity to study the properties of matter at extreme energy densities where a phase transition from the hadronic matter to a deconfined medium of quarks and gluons,

Schrödinger spectrum generated by the Cornell potential

Open Physics, 2015
The eigenvalues Ednl (a, c) of the d-dimensional Schrödinger equation with the Cornell potential V(r) = −a/r + c r, a, c > 0 are analyzed by means of the envelope method and the asymptotic iteration method (AIM).

Measurements of quarkonia production [PDF]

EPJ Web of Conferences
Quarkonium production in high-energy hadronic collisions is a useful tool to investigate fundamental aspects of Quantum Chromodynamics, from the proton and nucleus structure to deconfinement and the properties of the Quark Gluon Plasma (QGP).

Quarkonium Phenomenology from a Generalised Gauss Law

Universe, 2019
We present an improved analytic parametrisation of the complex in-medium heavy quark potential derived rigorously from the generalised Gauss law. To this end we combine in a self-consistent manner a non-perturbative vacuum potential with a weak-coupling ...

Entropic destruction of heavy quarkonium in quark-gluon plasma with gluon condensate

Physics Letters B, 2020
It has been argued that the peak of the quarkonium entropy at the deconfinement transition is related to the entropic force which induces dissociation of quarkonium states.
