A Short Theoretical Review of Charmonium Production

Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022
In this paper, we review the current status of the phenomenological study of quarkonium production in high‐energy collisions. After a brief introduction of several important models and effective field theories for quarkonium production, we discuss the comparisons between theoretical predictions and experimental measurements.

Bound State Solution Schrödinger Equation for Extended Cornell Potential at Finite Temperature

Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021
In this paper, we study the finite temperature‐dependent Schrödinger equation by using the Nikiforov‐Uvarov method. We consider the sum of the Cornell, inverse quadratic, and harmonic‐type potentials as the potential part of the radial Schrödinger equation.

Confinement of Fermions in Tachyon Matter at Finite Temperature

Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021
We study a phenomenological model that mimics the characteristics of QCD theory at finite temperature. The model involves fermions coupled with a modified Abelian gauge field in a tachyon matter. It reproduces some important QCD features such as confinement, deconfinement, chiral symmetry, and quark‐gluon‐plasma (QGP) phase transitions.

Event Shape and Multiplicity Dependence of Freeze‐Out Scenario and System Thermodynamics in Proton+Proton Collisions at s=13 TeV Using PYTHIA8

Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021
Recent observations of QGP‐like conditions in high‐multiplicity pp collisions from ALICE experiment at the LHC warrant an introspection whether to use pp collisions as a baseline measurement to characterize heavy‐ion collisions for the possible formation of a Quark‐Gluon Plasma.

Charmonium Properties Using the Discrete Variable Representation (DVR) Method

Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021
The Schrödinger equation is solved numerically for charmonium using the discrete variable representation (DVR) method. The Hamiltonian matrix is constructed and diagonalized to obtain the eigenvalues and eigenfunctions. Using these eigenvalues and eigenfunctions, spectra and various decay widths are calculated.

HEAVY QUARKONIUM [PDF]

Lepton and Photon Interactions at High Energies, 2004
I review heavy quarkonium physics in view of recent experimental results. In particular, I discuss new results on spin singlet states, photon and hadronic transitions, D–states and discovery of the yet unexplained narrow X(3872) state.

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 ...

Quarkonium Production At $Z^0$ and in $Υ(1S)$ Decay [PDF]

Int.J.Mod.Phys.A12:3931-3940,1997, 1996
The conventional color-singlet model was challenged by the recent data on quarkonium production. Discrepancies in production rates were observed at the Tevatron, at LEP, and in fixed-target experiments. The newly advocated color-octet mechanism provides a plausible solution to the anomalous quarkonium production observed at the Tevatron.

Spin Splitting Spectroscopy of Heavy Quark and Antiquarks Systems

Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020
Phenomenological potentials describe the quarkonium systems like cc¯,bb,¯ and b¯c where they give a good accuracy for the mass spectra. In the present work, we extend one of our previous works in the central case by adding spin‐dependent terms to allow for relativistic corrections.
