Quarkonium light-cone distribution amplitudes: twist structure and mass dependence

open access: yesJournal of High Energy Physics
We present a systematic study of the leading- and next-to-leading-twist light-cone distribution amplitudes (LCDAs) of ground-state pseudoscalar and vector quarkonium within the light-front quark model (LFQM).

Experimental overview: Quarkonium production in relativistic particle collisions [PDF]

open access: yesEPJ Web of Conferences
Quarkonium provides a golden probe of the formation of the Quark Gluon Plasma (QGP). Its production in heavy-ion collisions can be affected by an interplay of different phenomena such as medium-induced dissociation and heavy-quark (re)combination in the ...

Production & decay of quarkonium [PDF]

open access: yesAIP Conference Proceedings, 2002
In this talk I review NRQCD predictions for the production of charmonium at the Tevatron. After a quick presentation of the NRQCD factorization formalism for production and decay I review some old results and discuss how they compare to recent data. Following this I discuss some recent work done with Adam Leibovich and Ira Rothstein.

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

open access: yesPhysics 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

Born-Oppenheimer approximation in EFT and quarkonium hybrids

open access: yesEPJ Web of Conferences, 2017
We report on the results of [1] for the calculations of quarkonium hybrids. We have developed and Effective Field Theory (EFT) for quarkonium hybrids that systematically incorporates an expansion with respect to the adiabatic limit.

Boosting perturbative QCD stability in quarkonium production

open access: yesJournal of High Energy Physics, 2019
The aim of this paper is to introduce a general way to stabilize the perturbative QCD computations of heavy quarkonium production in the boosted or high-momentum transferring region with tree-level generators only.

Screening length of heavy quarkonia moving through a strongly coupled $$\mathcal {N}=4$$ N = 4 super Yang–Mills plasma in a magnetic field

open access: yesEuropean Physical Journal C: Particles and Fields
We investigate the influence of a constant magnetic field on the screening length of a heavy quarkonium propagating through a strongly coupled $$\mathcal {N}=4$$ N = 4 super Yang–Mills plasma.

Charmonium production measurements in small systems at LHCb [PDF]

open access: yesEPJ Web of Conferences
Charmonium production in hadronic collisions provides crucial insights into heavy quark interactions with nuclear media. In this work, we present comprehensive LHCb measurements of multiple quarkonium states in small collision systems.
