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.

Heavy Quarkonium Physics [PDF]

, 2004
This report is the result of the collaboration and research effort of the Quarkonium Working Group over the last three years. It provides a comprehensive overview of the state of the art in heavy-quarkonium theory and experiment, covering quarkonium spectroscopy, decay, and production, the determination of QCD parameters from quarkonium observables ...

Realizing the potential of quarkonium [PDF]

AIP Conference Proceedings, 1998
I recall the development of quarkonium quantum mechanics after the discovery of $Υ$. 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.

Sequential Quarkonium Suppression

, 2001
We use recent lattice data on the heavy quark potential in order to determine the dissociation temperatures of different quarkonium states in hot strongly interacting matter. Our analysis shows in particular that certain quarkonium states dissociate below the deconfinement point.

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.

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.

Study of Differential Scattering Cross‐Section Using Yukawa Term of Medium‐Modified Cornell Potential

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.

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
