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

Measurement of J/Ψ production in pp collisions at √s=7 TeV [PDF]

open access: yes, 2011
The production of J/psi mesons in proton-proton collisions at root s = 7 TeV is studied with the LHCb detector at the LHC. The differential cross-section for prompt J/psi production is measured as a function of the J/psi transverse momentum p(T) and ...

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.

Measurement of quarkonium production in ALICE

open access: yes, 2021
ALICE is designated to study the quark–gluon plasma (QGP), a state of matter where, due to high temperature and density, quarks and gluons are deconfined.

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

Systematics of quarkonium production

open access: yes, 1996
Quarkonium production in high-energy reactions is found to exhibit a behaviour more universal than that expected from velocity scaling. Total rates of quarkonia produced in hadronic interactions as well as Feynman-x and transverse momentum distributions ...

Prospects in quarkonium studies at LHCb [PDF]

open access: yes, 2010
Quarkonium production mechanism is not yet completely understood. CDF data have demonstrated that both Colour Singlet and Octet Model fail to explain the production of quarkonium prompt component.

Probing Heavy Quarkonium Production Mechnism: $\chi_c$ polarization

open access: yes, 2014
The necessicity of the color-octet mechanism in describing heavy quarkonium production is a longstanding puzzle. Compared to the yields of heavy quarkonium, its polarizations should be a sensitive observable to pin down the color-octet contributions.
