Space Dimension Renormdynamics

open access: yesParticles, 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.

Two-loop integrals for CP-even heavy quarkonium production and decays: elliptic sectors

open access: yesJournal of High Energy Physics, 2018
By employing the differential equations, we compute analytically the elliptic sectors of two-loop master integrals appearing in the NNLO QCD corrections to CP-even\ heavy quarkonium exclusive production and decays, which turns out to be the last and ...

Realizing the potential of quarkonium [PDF]

open access: yesAIP Conference Proceedings, 1998
I recall the development of quarkonium quantum mechanics after the discovery of $Υ$. I emphasize the empirical approach to determining the force between quarks from the properties of $c\bar{c}$ and $b\bar{b}$ bound states. I review the application of scaling laws, semiclassical methods, theorems and near-theorems, and inverse-scattering techniques.

Multiplicity Dependence of Quarkonium Production

open access: yesUniverse
Recent measurements on heavy-flavour production as a function of charged-particle multiplicity at the LHC are discussed. Focus is given to quarkonium results in small (pp or pPb) collision systems.

Quarkonium suppression in strongly coupled plasmas [PDF]

open access: yesEPJ Web of Conferences
Suppression of open heavy quarks and quarkonia in heavy-ion collisions are among the most informative probes of quark-gluon plasma (QGP). Interpreting the full wealth of data obtained from the collision events requires a precise theoretical understanding

Sequential Quarkonium Suppression

open access: yes, 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.

Quarkonium Level Spacings

open access: yesPhysics Letters B, 1977
Motivated by the apparent equal spacing M (ϒ′) - M (ϒ) = M ψi) - M (ψ), we show that the potential for which quarkonium level spacings are independent of quark mass, in the nonrelativistic limit, is V ( r ) = C In ( r / r 0 ). We enumerate consequences of the logarithmic potential and present an alternative interpretation of the data.
