Physical Review D, 2012 We extend our previous study of the vector charmonium states within a renormalization approach with boundary conditions to the full spectrum of charmonium and bottomonium. On the light of the predicted spectrum we comply to assignments suggested in the literature. A comparison with the regularized quark model is also included.

Simulation of Lindblad equations for quarkonium in the quark-gluon plasma [PDF]
Physical Review D, 2022 We study the properties of the Lindbladian quantum mechanical evolution of quarkonia with non-Abelian charges (color-singlet and octet) in the quark-gluon plasma.

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 ...

Entropic destruction of heavy quarkonium in a rotating hot and dense medium from holography [PDF]
Chinese Physics C, High Energy Physics & Nuclear Physics, 2022 Previous studies have indicated that the peak of the quarkonium entropy at the deconfinement transition can be related to the entropic force, which would induce the dissociation of heavy quarkonium.

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.

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.

Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 In the present work, we have studied the differential scattering cross‐section for ground states of charmonium and bottomonium in the frame work of the medium‐modified form of quark‐antiquark potential and Born approximation using the nonrelativistic quantum chromodynamics approach.

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

A Short Theoretical Review of Charmonium Production
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 In this paper, we review the current status of the phenomenological study of quarkonium production in high‐energy collisions. After a brief introduction of several important models and effective field theories for quarkonium production, we discuss the comparisons between theoretical predictions and experimental measurements.
