Dissociation of J/ψ and Y Using Dissociation Energy Criteria in N‐Dimensional Space

open access: yesAdvances in High Energy Physics, Volume 2024, Issue 1, 2024.
The analytical exact iteration method (AEIM) has been widely used to calculate N‐dimensional radial Schrodinger equation with medium‐modified form of Cornell potential and is generalized to the finite value of magnetic field (eB) with quasiparticle approach in hot quantum chromodynamics (QCD) medium.

Unquenching the Quark Model in a Nonperturbative Scheme

open access: yesAdvances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019
In recent years, the discovery in quarkonium spectrum of several states not predicted by the naive quark model has awakened a lot of interest. A possible description of such states requires the enlargement of the quark model by introducing quark‐antiquark pair creation or continuum coupling effects.

Quarkonium at Finite Temperature [PDF]

open access: yesNuclear Physics A, 2007
Lattice QCD studies on charmonium at finite temperature are presented After a discussion about problems for the Maximum Entropy Method applied to finite temperature lattice QCD, I show several results on charmonium spectral functions. The ``wave function'' of charmonium is also discussed to study the spatial correlation between quark and anti-quark in ...

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.

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

Direct quarkonium-plus-gluon production in DIS in the color glass condensate

open access: yesJournal of High Energy Physics
We compute the differential cross-section for direct quarkonium production accompanied by a gluon in high-energy deep inelastic scattering (DIS) at small-x.

Quarkonium Level Spacings

open access: yesPhysics Letters B, 1977
Motivated by the apparent equal spacing M (ϒ′) - M (ϒ) = M ψi) - M (ψ), we show that the potential for which quarkonium level spacings are independent of quark mass, in the nonrelativistic limit, is V ( r ) = C In ( r / r 0 ). We enumerate consequences of the logarithmic potential and present an alternative interpretation of the data.
