Quarkonium Production in the QGP [PDF]
Universe, 2019 We report on recent theory progress in understanding the production of heavy quarkonium in heavy-ion collisions based on the in-medium heavy-quark potential extracted from lattice QCD simulations. On the one hand, the proper in-medium potential allows us

Quarkonium spin alignment in a vortical medium [PDF]
Physical Review D, 2023 We use a potential model to investigate the phenomenology of quarkonium in a thermal rotating medium, where vorticity and spin density are not necessarily in equilibrium.

Impact of heavy quark and quarkonium data on nuclear gluon PDFs [PDF]
Physical Review D, 2022 A clear understanding of nuclear parton distribution functions (nPDFs) plays a crucial role in the interpretation of collider data taken at the Relativistic Heavy Ion Collider (RHIC), the Large Hadron Collider (LHC) and in the near future at the Electron-

Heavy quarkonium dynamics at next-to-leading order in the binding energy over temperature [PDF]
Journal of High Energy Physics, 2022 Using the potential non-relativistic quantum chromodynamics (pNRQCD) effective field theory, we derive a Lindblad equation for the evolution of the heavy-quarkonium reduced density matrix that is accurate to next-to-leading order (NLO) in the ratio of ...

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 ...

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.

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 ...

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.

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.
