Long-Range Forces of QCD [PDF]

, 1999
We consider the scattering of two color dipoles (e.g., heavy quarkonium states) at low energy - a QCD analog of Van der Waals interaction. Even though the couplings of the dipoles to the gluon field can be described in perturbation theory, which leads to

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

European 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.

Polarized gluon studies with charmonium and bottomonium at LHCb and AFTER [PDF]

, 2012
Recently it has been put forward that linearly polarized gluons inside unpolarized protons affect the transverse momentum distribution of final state particles in hadronic collisions.

Quarkonium transport in weakly and strongly coupled plasmas [PDF]

EPJ 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 ...

Gluon fragmentation into heavy quarkonium [PDF]

Physical 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 $D(z, )$ describing these processes can be calculated using perturbative QCD.

Transverse Momentum Dependent Factorization for Quarkonium Production at Low Transverse Momentum

, 2013
Quarkonium production in hadron collisions at low transverse momentum $q_\perp \ll M$ with $M$ as the quarkonium mass can be used for probing transverse momentum dependent (TMD) gluon distributions.

Two-photon and two-gluon decays of p-wave heavy quarkonium using a covariant light-front approach [PDF]

, 2010
In this paper, a study of two-photon and two-gluon decays in the context of p-wave heavy quarkonia is presented. Within the covariant light-front framework, the annihilation rates of scalar and tensor quarkonium states are derived. In the absence of free

Complete NLO QCD study of single- and double-quarkonium hadroproduction in the colour-evaporation model at the Tevatron and the LHC

Physics Letters B, 2020
We study the Single-Parton-Scattering (SPS) production of double quarkonia (J/ψ+J/ψ, J/ψ+ϒ, and ϒ+ϒ) in pp and pp¯ collisions at the LHC and the Tevatron as measured by the CMS, ATLAS, LHCb, and D0 experiments in the Colour-Evaporation Model (CEM), based
