Quarkonium polarization as a test of non-relativistic effective theory [PDF]
arXiv, 1997 I compare current approaches to quarkonium production with regard to what they tell us about quarkonium polarization. Predictions for $J/\psi$ polarization in hadron-hadron and photon-hadron collisions are summarized.

QUARKONIUM AT FINITE TEMPERATURE [PDF]
, 2010 We discuss properties of heavy quarkonium states at high temperatures based on lattice QCD and potential models. We review recent progress made in lattice calculations of spatial static quark anti-quark correlators as well as quarkonium correlators in Euclidean time.

The dipole picture and the non-relativistic expansion [PDF]
SciPost Physics Proceedings, 2022 We study exclusive quarkonium production in the dipole picture at next-to-leading order (NLO) accuracy, using the non-relativistic expansion for the quarkonium wavefunction.

Sequential Quarkonium Suppression
, 2001 We use recent lattice data on the heavy quark potential in order to determine the dissociation temperatures of different quarkonium states in hot strongly interacting matter. Our analysis shows in particular that certain quarkonium states dissociate below the deconfinement point.

The complex heavy quarkonium potential with the Gribov–Zwanziger action [PDF]
The European Physical Journal C, 2023 Gribov–Zwanziger prescription in Yang–Mills theory improves the infrared dynamics. In this work, we study the static potential of a heavy quark-antiquark pair with the HTL resummed perturbation method within the Gribov–Zwanziger approach at finite ...

Hyperfine splittings of heavy quarkonium hybrids [PDF]
Physical Review D, 2023 In the framework of the Born-Oppenheimer Effective Field Theory, the hyperfine structure of heavy quarkonium hybrids at leading order in the 1/m Q expansion is determined by two potentials.

Real time quarkonium transport coefficients in open quantum systems from Euclidean QCD [PDF]
Physical Review D, 2023 Recent open quantum system studies showed that quarkonium time evolution inside the quark-gluon plasma is determined by transport coefficients that are defined in terms of a gauge invariant correlator of two chromoelectric field operators connected by an

Quarkonium spin alignment in a vortical medium [PDF]
Physical Review D, 2023 We use a potential model to investigate the phenomenology of quarkonium in a thermal rotating medium, where vorticity and spin density are not necessarily in equilibrium.

Impact of heavy quark and quarkonium data on nuclear gluon PDFs [PDF]
Physical Review D, 2022 A clear understanding of nuclear parton distribution functions (nPDFs) plays a crucial role in the interpretation of collider data taken at the Relativistic Heavy Ion Collider (RHIC), the Large Hadron Collider (LHC) and in the near future at the Electron-

Heavy quarkonium dynamics at next-to-leading order in the binding energy over temperature [PDF]
Journal of High Energy Physics, 2022 Using the potential non-relativistic quantum chromodynamics (pNRQCD) effective field theory, we derive a Lindblad equation for the evolution of the heavy-quarkonium reduced density matrix that is accurate to next-to-leading order (NLO) in the ratio of ...
