Quarkonia as probes of initial and final states in small systems with ALICE [PDF]

EPJ Web of Conferences
The multiple parton−parton interactions (MPIs) are an important element to describe the observed collective flow and strangeness enhancement in high multiplicity pp and p−Pb collisions, the so-called small systems.

Excitation Function of Initial Temperature of Heavy Flavor Quarkonium Emission Source in High Energy Collisions

Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020
The transverse momentum spectra of J/ψ, ψ(2S), and Y(nS, n = 1, 2, 3) produced in proton‐proton (p + p), proton‐antiproton p+p¯, proton‐lead (p + Pb), gold‐gold (Au + Au), and lead‐lead (Pb + Pb) collisions over a wide energy range are analyzed by the (two‐component) Erlang distribution, the Hagedorn function (the inverse power‐law), and the Tsallis ...

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.

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 $f_J(1710)$.

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

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.

Theory of Quarkonia as Probes for Deconfinement [PDF]

EPJ Web of Conferences
This is a plenary talk given at Quark Matter 2025, summarizing recent theoretical developments for the understanding of quarkonium production in relativistic heavy ion collisions and how quarkonium uniquely probes the deconfined phase of QCD matter.

Heavy Quarkonium Physics

, 2004
This report is the result of the collaboration and research effort of the Quarkonium Working Group over the last three years. It provides a comprehensive overview of the state of the art in heavy-quarkonium theory and experiment, covering quarkonium spectroscopy, decay, and production, the determination of QCD parameters from quarkonium observables ...
