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.

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.

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

Journal of High Energy Physics, 2017
By employing the method of differential equations, we compute the various types of two-loop master integrals involved in CP-even heavy quarkonium exclusive production and decays.

Suppression of quarkonium production in heavy ion collisions at RHIC and LHC [PDF]

, 2005
A model for the production of quarkonium states in the midrapidity region at RHIC and LHC energy range is presented which explores well understood properties of QCD only. An increase of the quarkonium hadronisation time with the initial energy leads to a

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.

Heavy Hybrids: decay to and mixing with Heavy Quarkonium

EPJ Web of Conferences, 2017
We report on a recent QCD based research on hybrid mesons containing cc̄ or bb̄ quarks. We present results for the spectrum, the decay widths to heavy quarkonium, and the role of mixing with the latter.

Deconfinement and quarkonium suppression [PDF]

The European Physical Journal C, 2005
Modifications in the production pattern of heavy quark bound states have long been considered to provide sensitive signatures for the thermal properties of dense matter created in heavy ion collisions. The original concept of Matsui and Satz for quarkonium suppression as signature for deconfinement in heavy ion collisions has been challenged recently ...

Heavy Quarkonium States With Baryonic Chemical Potential

Advances in High Energy Physics
In this work, we have studied the dissociation behavior of 1S and 2S states of quarkonium using quasiparticle approach where the Debye mass depends on baryonic chemical potential.
