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.

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.

Realizing the potential of quarkonium [PDF]
AIP Conference Proceedings, 1998 I recall the development of quarkonium quantum mechanics after the discovery of $ $. I emphasize the empirical approach to determining the force between quarks from the properties of $c\bar{c}$ and $b\bar{b}$ bound states. I review the application of scaling laws, semiclassical methods, theorems and near-theorems, and inverse-scattering techniques.

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.

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.

Order-v^4 Corrections to S-wave Quarkonium Decay [PDF]
Phys.Rev. D66 (2002) 094011, 2002 We compute corrections of relative order v^4 to the rates for the decays of ^1S_0 heavy quarkonium into two photons and into light hadrons and for the decays of ^3S_1 heavy quarkonium into a lepton pair and into light hadrons. In particular, we compute the coefficients of the decay operators that have the same quantum numbers as the heavy quarkonium ...

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 The rapidity dependent transverse momentum spectra of heavy quarkonia (J/ψ and Υ mesons) produced in small collision systems such as proton‐proton (pp) and proton‐lead (p‐Pb) collisions at center‐of‐mass energy (per nucleon pair) s (sNN) = 5‐13 TeV are described by a two‐component statistical model which is based on the Tsallis statistics and inverse ...
