Sequential Quarkonium Suppression

, 2001
We use recent lattice data on the heavy quark potential in order to determine the dissociation temperatures of different quarkonium states in hot strongly interacting matter. Our analysis shows in particular that certain quarkonium states dissociate below the deconfinement point.

Production & decay of quarkonium [PDF]

AIP 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

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

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.

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.

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.

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 ...
