Charmonium production measurements in small systems at LHCb [PDF]

EPJ 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.

Boosting perturbative QCD stability in quarkonium production

Journal 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.

Quarkonium: a theory overview [PDF]

, 2018
International audienceQuarkonium 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.

Quarkonium production and polarization in pp collisions with the CMS detector

EPJ Web of Conferences, 2014
Studies of the production of heavy quarkonium states are very important to improve our understanding of QCD and hadron formation, given that the heavy quark masses allow the application of theoretical tools less sensitive to nonperturbative effects ...

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

European 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.

Born-Oppenheimer approximation in EFT and quarkonium hybrids

EPJ 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.

The effect of chemical potential on imaginary potential and entropic force

Physics Letters B, 2017
Imaginary potential and entropic force represent different mechanisms for melting the heavy quarkonium. In this paper, we study the chemical potential effect on these two quantities with respect to a moving quarkonium from the AdS/CTF duality. We observe

Universal kinematic scaling as a probe of factorized long-distance effects in high-energy quarkonium production

European Physical Journal C: Particles and Fields, 2018
Dimensional analysis reveals general kinematic scaling rules for the momentum, mass, and energy dependence of Drell–Yan and quarkonium cross sections.
