Properties and Behaviors of Heavy Quarkonia: Insights through Fractional Model and Topological Defects

Advances in High Energy Physics, Volume 2024, Issue 1, 2024.
In this study, we investigated the impact of a topological defect (λ) on the properties of heavy quarkonia using the extended Cornell potential. We solved the fractional radial Schrödinger equation (SE) using the extended Nikiforov‐Uvarov (ENU) method to obtain the eigenvalues of energy, which allowed us to calculate the masses of charmonium and ...

High-energy dileptons from an anisotropic quark-gluon plasma

, 2009
We calculate leading-order dilepton yields from a quark-gluon plasma which has a time-dependent anisotropy in momentum space. Such anisotropies can arise during the earliest stages of quark-gluon plasma evolution due to the rapid longitudinal expansion ...

Jet quenching of the heavy quarks in the quark-gluon plasma and the nonadditive statistics

Physics Letters B
Using the Plastino-Plastino (PP) equation, we calculate transport coefficients of the heavy-quarks traversing inside the quark-gluon plasma, and generalize their relationship with differential energy loss. The PP equation indicates anomalous diffusion of

Charmonium production and elliptic flow in relativistic heavy-ion collisions

EPJ Web of Conferences, 2011
Using the two-component model for charmonium production, which includes contributions from both initial hard nucleon-nucleon scattering and from regeneration in the quark-gluon plasma, we have studied the nuclear modification factor RAA and elliptic flow

Quarkonium states in an anisotropic quark-gluon plasma

, 2009
In this work we study the properties of quarkonium states in a quark-gluon plasma which, due to expansion and non-zero viscosity, exhibits a local anisotropy in momentum space.

Kollektive Phänomene im Nichtgleichgewichts-Quark-Gluon-Plasma

, 2008
In this work we study the non-equilibrium dynamics of a quark-gluon plasma, as created in heavy-ion collisions. We investigate how big of a role plasma instabilities can play in the isotropization and equilibration of a quark-gluon plasma. In particular,

Phenomenological aspects of an anisotropic quark-gluon plasma

, 2010
In this work we investigate phenomenological aspects of an anisotropic quark-gluon plasma. In the first part of this thesis, we formulate phenomenologicalmodels that take into account the momentumspace anisotropy of the system developed during the ...

Dynamic scaling and quenching for heavy quark in the linear expanding medium

European Physical Journal C: Particles and Fields
We study the energy loss of the heavy quark and the heavy quark jet propagating through linear expanding quark–gluon plasma (QGP). We show that the concept of scaling is valid for heavy quarks, with the quenching parameter of the equivalent static media ...
