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

open access: yesAdvances 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

open access: yesAdvances 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

open access: yesAdvances 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

open access: yesAdvances 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.

Inclusive quarkonium production in pp collisions at $$\sqrt{s}$$ s = 5.02 TeV [PDF]

open access: yesThe European Physical Journal C, 2021
This article reports on the inclusive production cross section of several quarkonium states, $$\textrm{J}/\psi $$ J / ψ , $$\psi \mathrm{(2S)}$$ ψ ( 2 S ) , $$\Upsilon \mathrm (1S)$$ Υ ( 1 S ) , $$\Upsilon \mathrm{(2S)}$$ Υ ( 2 S ) , and $$\Upsilon ...

Rigorous QCD analysis of inclusive annihilation and production of heavy quarkonium. [PDF]

open access: yesPhysical Review D, Particles and fields, 1994
A rigorous QCD analysis of the inclusive annihilation decay rates of heavy quarkonium states is presented. The effective-field-theory framework of nonrelativistic QCD is used to separate the short-distance scale of annihilation, which is set by the heavy

Non-Abelian electric field correlator at NLO for dark matter relic abundance and quarkonium transport [PDF]

open access: yesJournal of High Energy Physics, 2021
We perform a complete next-to-leading order calculation of the non-Abelian electric field correlator in a SU( N c ) plasma, which encodes properties of the plasma relevant for heavy particle bound state formation and dissociation, and is different from ...

Deconfinement and quarkonium suppression [PDF]

open access: yesThe 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 ...

Approximate solutions of the Schrödinger equation with Hulthén-Hellmann Potentials for a Quarkonium system [PDF]

open access: yesRevista mexicana de física, 2021
Hulthén plus Hellmann potentials are adopted as the quark-antiquark interaction potential for studying the mass spectra of heavy mesons. We solved the radial Schrödinger equation analytically using the Nikiforov-Uvarov method.
