Bound state calculations for Hulthén–Hellmann type potential by improved asymptotic iteration method
International Journal of Quantum Chemistry, Volume 123, Issue 23, December 5, 2023., 2023 Coulomb and Hulthén–Hellmann potential versus r for A = 0.002, B = 2, C = 1, α = 0.001 Abstract In this study, some nonrelativistic energy eigenvalues of Hulthén–Hellmann type interaction were calculated using the improved asymptotic iteration method (improved AIM) by applying the Greene–Aldrich approach for the inverse square term of the potential ...

Quarkonia as probes of the QGP and of the initial stages of the heavy-ion collision with ALICE [PDF]
EPJ Web of Conferences, 2022 Studies of quarkonium production in heavy-ion collisions can be used for probing QGP properties. The suppression and regeneration of bound quarkonium states is sensitive to the medium properties.

Anisotropic Behavior of S‐Wave and P‐Wave States of Heavy Quarkonia at Finite Magnetic Field
Advances in High Energy Physics, Volume 2023, Issue 1, 2023., 2023 We studied the effect of momentum space anisotropy on heavy quarkonium states using an extended magnetized effective fugacity quasiparticle model (EQPM). Both the real and imaginary part of the potential has been modified through the dielectric function by including the anisotropic parameter ξ.

Nonequilibrium evolution of quarkonium in medium [PDF]
EPJ Web of Conferences, 2022 We review recent progress in open quantum system approach to the description of quarkonium in the quark-gluon plasma. A particular emphasis is put on the Lindblad equations for quarkonium and its numerical simulations.

Fractional Effective Quark‐Antiquark Interaction in Symplectic Quantum Mechanics
Advances in High Energy Physics, Volume 2023, Issue 1, 2023., 2023 Considering the formalism of symplectic quantum mechanics, we investigate a two‐dimensional nonrelativistic strong interacting system, describing a bound heavy quark‐antiquark state. The potential has a linear component that is analyzed in the context of generalized fractional derivatives.

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

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

Quarkonium semiclassical transport in quark-gluon plasma: factorization and quantum correction
Journal of High Energy Physics, 2021 We study quarkonium transport in the quark-gluon plasma by using the potential nonrelativistic QCD (pNRQCD) effective field theory and the framework of open quantum systems. We argue that the coupling between quarkonium and the thermal bath is weak using

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.
