Heavy Quarkonium Physics from Effective Field Theories [PDF]
, 2006 I review recent progress in heavy quarkonium physics from an effective field theory perspective. In this unifying framework, I discuss advances in perturbative calculations for low-lying quarkonium observables and in lattice calculations for high-lying ...

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 ...

Quarkonium Production in the QGP
Universe, 2019 We report on recent theory progress in understanding the production of heavy quarkonium in heavy-ion collisions based on the in-medium heavy-quark potential extracted from lattice QCD simulations. On the one hand, the proper in-medium potential allows us

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.

Quarkonium correlators and spectral functions at zero and finite temperature [PDF]
, 2006 We study quarkonium correlators and spectral functions at zero and finite temperature using the anisotropic Fermilab lattice formulation with anisotropy xi=2 and 4. To control cutoff effects we use several different lattice spacings.

Space Dimension Renormdynamics
Particles, 2020 We aim to construct a potential better suited for studying quarkonium spectroscopy. We put the Cornell potential into a more geometrical setting by smoothly interpolating between the observed small and large distance behaviour of the quarkonium potential.

Entropic destruction of a moving heavy quarkonium
, 2015 Recently it has been shown that the peak of the quarkonium entropy at the deconfinement transition is related to the emergent entropic force which destructs the quarkonium.

Next-to-leading-log renormalization-group running in heavy-quarkonium creation and annihilation [PDF]
, 2001 In the framework of potential NRQCD, we obtain the next-to-leading-log renormalization-group running of the matching coefficients for the heavy quarkonium production currents near threshold.
