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.

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.

A Short Theoretical Review of Charmonium Production

Advances in High Energy Physics, 2022
In this paper, we review the current status of the phenomenological study of quarkonium production in high-energy collisions. After a brief introduction of several important models and effective field theories for quarkonium production, we discuss the ...

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 ...

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.

An effective field theory approach to quarkonium at small transverse momentum

Journal of High Energy Physics, 2020
In this work we apply effective field theory (EFT) to observables in quarkonium production and decay that are sensitive to soft gluon radiation, in particular measurements that are sensitive to small transverse momentum. Within the EFT framework we study
