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.

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.

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.

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

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

Bound State Solution Schrödinger Equation for Extended Cornell Potential at Finite Temperature
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 In this paper, we study the finite temperature‐dependent Schrödinger equation by using the Nikiforov‐Uvarov method. We consider the sum of the Cornell, inverse quadratic, and harmonic‐type potentials as the potential part of the radial Schrödinger equation.

Confinement of Fermions in Tachyon Matter at Finite Temperature
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 We study a phenomenological model that mimics the characteristics of QCD theory at finite temperature. The model involves fermions coupled with a modified Abelian gauge field in a tachyon matter. It reproduces some important QCD features such as confinement, deconfinement, chiral symmetry, and quark‐gluon‐plasma (QGP) phase transitions.

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

Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 Recent observations of QGP‐like conditions in high‐multiplicity pp collisions from ALICE experiment at the LHC warrant an introspection whether to use pp collisions as a baseline measurement to characterize heavy‐ion collisions for the possible formation of a Quark‐Gluon Plasma.
