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.

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.

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.
