Entropic destruction of heavy quarkonium in a rotating hot and dense medium from holography [PDF]

Chinese Physics C, High Energy Physics & Nuclear Physics, 2022
Previous studies have indicated that the peak of the quarkonium entropy at the deconfinement transition can be related to the entropic force, which would induce the dissociation of heavy quarkonium.

Study of Differential Scattering Cross‐Section Using Yukawa Term of Medium‐Modified Cornell Potential

Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022
In the present work, we have studied the differential scattering cross‐section for ground states of charmonium and bottomonium in the frame work of the medium‐modified form of quark‐antiquark potential and Born approximation using the nonrelativistic quantum chromodynamics approach.

Quarkonium production and polarization: where do we stand? [PDF]

EPJ Web of Conferences, 2022
We review the current status of heavy quarkonium production phenomenology based on nonrelativistic effective field theories, focusing on spintriplet S -wave states such as J/ψ, ψ(2S ), and ϒ.

Quarkonium suppression in the open quantum system approach [PDF]

Suplemento de la Revista Mexicana de Física, 2022
Quarkonium suppression in relativistic heavy ion collisions has been studied experimentally for decades to probe the properties of the quark-gluon plasma. For this purpose, complete theoretical understanding of the time evolution of quarkonium inside the

Quark‐Antiquark Effective Potential in Symplectic Quantum Mechanics

Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022
In this paper, we study within the structure of Symplectic Quantum Mechanics a bidimensional nonrelativistic strong interaction system which represent the bound state of heavy quark‐antiquark, where we consider a Cornell potential which consists of Coulomb‐type plus linear potentials. First, we solve the Schrödinger equation in the phase space with the

Probing the Hot QCD Matter via Quarkonia at the Next-Generation Heavy-Ion Experiment at LHC

Particles, 2023
Quarkonia represent one of the most valuable probes of the deconfined quark–gluon hot medium since the very first experimental studies with ultrarelativistic heavy-ion collisions. A significant step forward in characterizing the QCD matter via systematic

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.

Heavy Quarkonium Physics

, 2004
This report is the result of the collaboration and research effort of the Quarkonium Working Group over the last three years. It provides a comprehensive overview of the state of the art in heavy-quarkonium theory and experiment, covering quarkonium spectroscopy, decay, and production, the determination of QCD parameters from quarkonium observables ...
