, 2017 In this addendum to Phys.\ Rev.\ D {\bf 95}, 054018 (2017) we recompute the rates for the decays of the Higgs boson to a vector quarkonium plus a photon, where the vector quarkonium is $J/\psi$, $\Upsilon(1S)$, $\Upsilon(2S)$, or $\Upsilon(3S)$.

Cornell Potential: A Neural Network Approach
Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 We solved Schrödinger equation with Cornell potential (Coulomb‐plus‐linear potential) by using neural network approach. Four different cases of Cornell potential for different potential parameters were used without a physical relevance. Besides that charmonium, bottomonium and bottom‐charmed spin‐averaged spectra were also calculated.

b-quark and quarkonium production and polarisation
EPJ Web of Conferences, 2013 An overview is given of recent measurements of open beauty and heavy quarkonium production and quarkonium polarisation, made by the ATLAS, CMS and LHCb collaborations at the Large Hadron Collider.

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

Physics 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.

Quarkonium correlators at finite temperature and potential models [PDF]
, 2007 We discuss the calculations of quarkonium spectral functions in potential models and their implications for the interpretation of the lattice data on quarkonium correlators. In particular, we find that melting of different quarkonium states does not lead

Double Charmonium Productions in Electron‐Positron Annihilation Using Bethe‐Salpeter Approach
Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 We calculate the double charmonium production cross‐section within the framework of 4 × 4 Bethe‐Salpeter Equation in the electron‐positron annihilation, at center of mass energy s=10.6GeV, that proceeds through the exchange of a single virtual photon.

Nonlinear Behavior of Quarkonium Formation and Deconfinement Signals [PDF]
, 2002 We anticipate new features of quarkonium production in heavy ion collisions at RHIC and LHC energies which differ from a straightforward extrapolation of results at CERN SPS energy.

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 In this paper, quarkonium dissociation is investigated in an anisotropic plasma in the hot and dense media. For that purpose, the multidimensional Schrödinger equation is solved analytically by Nikiforov‐Uvarov (NU) method for the real part of the potential in an anisotropic medium. The binding energy and dissociation temperature are calculated.
