Quarkonium spectroscopy of the linear plus modified Yukawa potential [PDF]
Physica Scripta, 2022 In this article, the linear plus modified Yukawa potential (LIMYP) is used as the quark-antiquark interaction potential for the approximate analytical bound state solution of the Klein-Gordon equation in three-dimensional space.

Entropic force and real-time dynamics of holographic quarkonium in a magnetic field [PDF]
Physical Review D, 2022 We continue the study of a recently constructed holographic QCD model supplemented with magnetic field. We consider the holographic dual of a quark, anti-quark pair and investigate its entropy beyond the deconfinement phase transition in terms of ...

QCD analysis of near-threshold photon-proton production of heavy quarkonium [PDF]
Physical Review D, 2021 The near-threshold photo or electroproduction of heavy vector quarkonium off the proton is studied in quantum chromodynamics. Similar to the high-energy limit, the production amplitude can be factorized in terms of gluonic generalized parton ...

Two-loop master integrals for pseudo-scalar quarkonium and leptonium production and decay [PDF]
Journal of High Energy Physics, 2022 We compute the master integrals relevant for the two-loop corrections to pseudo-scalar quarkonium and leptonium production and decay. We present both analytic and high-precision numerical results.

Effect of a Wake-Field on the Dissociation of Quarkonium in Collisional Quark–Gluon Plasma
Particles, 2023 We have studied wake effects on the dissociation of heavy quarkonia states J/ψ and Y by introducing an in-medium modification to the inter-quark potential.

Indirect constraints on lepton-flavor-violating quarkonium decays [PDF]
Physical Review D, 2022 Within an effective-field-theory framework, we present a model-independent analysis of the potential of discovering new physics by searching for lepton flavour violation in heavy quarkonium decays and, more in general, we study the phenomenology of lepton ...

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.

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 ...

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.

Quarkonium suppression in the open quantum system approach [PDF]
Suplemento de la Revista Mexicana de Física, 2022 Quarkonium suppression in relativistic heavy ion collisions has been studied experimentally for decades to probe the properties of the quark-gluon plasma. For this purpose, complete theoretical understanding of the time evolution of quarkonium inside the
