Associated-quarkonium production [PDF]

PoS DIS2014 (2014) 151, 2014
We discuss the growing interest to measure associated-quarkonium production in a number of channels at the LHC. Whereas back-to-back production of quarkonium + isolated photon provides a unique way to extract gluon TMDs, observables such as quarkonium + W/Z can be of great help to better understand the quarkonium production mechanism as well as to shed

Heavy Quarkonium Physics [PDF]

arXiv: High Energy Physics - Phenomenology, 2004
This report is the result of the collaboration and research effort of the Quarkonium Working Group over the last three years. It provides a comprehensive overview of the state of the art in heavy-quarkonium theory and experiment, covering quarkonium spectroscopy, decay, and production, the determination of QCD parameters from quarkonium observables ...

Quarkonium: a theory overview [PDF]

Nuclear Physics A, 2018
Quarkonium has long been proposed as one of the golden probes to identify the phase transition from confined hadronic matter to the deconfined quark-gluon plasma in heavy-ion collisions. Since then, we have achieved a better understanding, not only about the propagation of quarkonium in-medium, but also about its production.

Breakdown of QCD factorization for P-wave quarkonium production at low transverse momentum [PDF]

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.

Entropic destruction of a moving heavy quarkonium [PDF]

Phys. Rev. D 94, 026007 (2016), 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. Using the AdS/CFT correspondence, we consider dissociation of a moving heavy quarkonium by entropic force.

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

Journal 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 ...

Quarkonium formation time in quark-gluon plasma [PDF]

, 2013
The quarkonium formation time in a quark-gluon plasma (QGP) is determined from the space-time correlator of heavy quark vector currents using the quarkonium in-medium mass and wave function obtained from heavy quark potentials extracted from the lattice QCD.

Quarkonium correlators at finite temperature and potential models [PDF]

PoSLAT2007:216,2007, 2007
We discuss the calculations of quarkonium spectral functions in potential models and their implications for the interpretation of the lattice data on quarkonium correlators. In particular, we find that melting of different quarkonium states does not lead to significant change in the Euclidean time correlators.

Nucleon-Quarkonium Elastic Scattering and the Gluon Contribution to Nucleon Spin [PDF]

Phys.Rev.Lett. 82 (1999) 4985-4987, 1999
It is shown that the amplitude for the scattering of a heavy quarkonium system from a nucleon near threshold is completely determined by the fraction of angular momentum, as well as linear momentum, carried by gluons in the nucleon. A form for the quarkonium-nucleon non-relativistic potential is derived.
