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.

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.

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.

Charmonium and exotics from lattice QCD [PDF]
EPJ Web of Conferences, 2019 We review selected lattice results on the charmonium spectrum and first attempts to search for the existence of exotic states. The hadro-quarkonium model was proposed to interpret some of the exotic states as a quarkonium core inside a hadron. We present

Quarkonium production in Pb-Pb collisions at √SNN = 5.02 TeV with ALICE
EPJ Web of Conferences, 2018 Ultra-relativistic heavy-ion collisions at the Large Hadron Collider provide a unique opportunity to study the properties of matter at extreme energy densities where a phase transition from the hadronic matter to a deconfined medium of quarks and gluons,

Schrödinger spectrum generated by the Cornell potential
Open Physics, 2015 The eigenvalues Ednl (a, c) of the d-dimensional Schrödinger equation with the Cornell potential V(r) = −a/r + c r, a, c > 0 are analyzed by means of the envelope method and the asymptotic iteration method (AIM).

Measurements of quarkonia production [PDF]
EPJ Web of ConferencesQuarkonium production in high-energy hadronic collisions is a useful tool to investigate fundamental aspects of Quantum Chromodynamics, from the proton and nucleus structure to deconfinement and the properties of the Quark Gluon Plasma (QGP).

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.
