The dynamics of quarkonium production [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1999
Quarkonium production is a sensitive probe of the dynamics of hard scattering, which can `measure' the environment of the heavy quark pair after it is created in a hard process. Quarkonium hadroproduction data indicates that the produced pair experiences a secondary, hard interaction and then ceases to interact at a stage when the pair is still compact

Gluon fragmentation into heavy quarkonium [PDF]

open access: yesPhysical Review Letters, 1993
The dominant production mechanism for heavy quark-antiquark bound states in very high energy processes is fragmentation, the splitting of a high energy parton into a quarkonium state and other partons. We show that the fragmentation functions $D(z,μ)$ describing these processes can be calculated using perturbative QCD.

QUARKONIUM AT FINITE TEMPERATURE [PDF]

open access: yes, 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.

Quarkonium at Finite Temperature [PDF]

open access: yesNuclear Physics A, 2007
Lattice QCD studies on charmonium at finite temperature are presented After a discussion about problems for the Maximum Entropy Method applied to finite temperature lattice QCD, I show several results on charmonium spectral functions. The ``wave function'' of charmonium is also discussed to study the spatial correlation between quark and anti-quark in ...

Entropic Destruction of Heavy Quarkonium from a Deformed AdS5 Model

open access: yesAdvances in High Energy Physics, 2017
We study the destruction of heavy quarkonium due to the entropic force in a deformed AdS5 model. The effects of the deformation parameter on the interdistance and the entropic force are investigated.

Heavy quarkonia in a potential model: binding energy, decay width, and survival probability

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
Recently a lot of progress has been made in deriving the heavy quark potential within a QCD medium. In this article we have considered heavy quarkonium in a hot quark gluon plasma phase.

Deconfinement and quarkonium suppression [PDF]

open access: yesThe European Physical Journal C, 2005
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 ...

Quarkonium transport in weakly and strongly coupled plasmas [PDF]

open access: yesEPJ Web of Conferences
We report on progress in the nonperturbative understanding of quarkonium dynamics inside a thermal plasma. The time evolution of small-size quarkonium is governed by two-point correlation functions of chromoelectric fields dressed with an adjoint Wilson ...
