Approximate solutions of the Schrödinger equation with Hulthén-Hellmann Potentials for a Quarkonium system [PDF]
Hulthén plus Hellmann potentials are adopted as the quark-antiquark interaction potential for studying the mass spectra of heavy mesons. We solved the radial Schrödinger equation analytically using the Nikiforov-Uvarov method.

Non-Abelian electric field correlator at NLO for dark matter relic abundance and quarkonium transport [PDF]
We perform a complete next-to-leading order calculation of the non-Abelian electric field correlator in a SU( N c ) plasma, which encodes properties of the plasma relevant for heavy particle bound state formation and dissociation, and is different from ...

Deconfinement and quarkonium suppression [PDF]
Modifications in the production pattern of heavy quark bound states have long been considered to provide sensitive signatures for the thermal properties of dense matter created in heavy ion collisions. The original concept of Matsui and Satz for quarkonium suppression as signature for deconfinement in heavy ion collisions has been challenged recently ...

Charmonium and exotics from lattice QCD [PDF]
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

Comparative study of quarkonium transport in hot QCD matter [PDF]
This document summarizes the efforts of the EMMI Rapid Reaction Task Force on “Suppression and (re)generation of quarkonium in heavy-ion collisions at the LHC”, centered around their 2019 and 2022 meetings.

A dynamical Einstein-Born-Infeld-dilaton model and holographic quarkonium melting in a magnetic field [PDF]
We generalize the potential reconstruction method to set up a dynamical Einstein-Born-Infeld-dilaton model, which we then use to study holographic quarkonium melting in an external magnetic field.

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.

Shedding Light on Hadronization by Quarkonium Energy Correlator. [PDF]
We propose to measure the energy correlator in quarkonium production, which tracks the energy deposited in the calorimeter at the χ-angular distance away from the identified quarkonium.

Quarkonium: a theory overview [PDF]
Quarkonium has long been proposed as one of the golden probes to identify the phase transition from confined hadronic matter to the deconfined quark-gluon plasma in heavy-ion collisions. Since then, we have achieved a better understanding, not only about the propagation of quarkonium in-medium, but also about its production.
