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 ConferencesThis 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.

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.

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
