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 ...

Fermionic Collective Modes of an Anisotropic Quark-Gluon Plasma

, 2006
We determine the fermionic collective modes of a quark-gluon plasma which is anisotropic in momentum space. We calculate the fermion self-energy in both the imaginary- and real-time formalisms and find that numerically and analytically (for two special ...

Two-loop HTL Thermodynamics with Quarks [PDF]

, 2003
We calculate the quark contribution to the free energy of a hot quark-gluon plasma to two-loop order using hard-thermal-loop (HTL) perturbation theory.

Induced photon emission from quark jets in ultrarelativistic heavy-ion collisions

, 2004
We study the induced photon bremsstrahlung from a fast quark produced in AA-collisions due to multiple scattering in quark-gluon plasma. For RHIC and LHC conditions the induced photon spectrum is sharply peaked at photon energy close to the initial quark

QUARK GLUON PLASMA - RECENT ADVANCES [PDF]

International Journal of Modern Physics A, 2002
While heavy ion collisions at the SPS have produced excited strongly interacting matter near the conditions for quark deconfinement, the RHIC may be the first machine capable of creating quark-antiquark plasmas sufficiently long-lived to allow deep penetration into the new phase.

Non-Perturbative Dilepton Production from a Quark-Gluon Plasma

, 1999
The dilepton production rate from the quark-gluon plasma is calculated from the imaginary part of the photon self energy using a quark propagator that contains the gluon condensate.

Matching pre-equilibrium dynamics and viscous hydrodynamics

, 2010
We demonstrate how to match pre-equilibrium dynamics of a 0+1 dimensional quark gluon plasma to 2nd-order viscous hydrodynamical evolution. The matching allows us to specify the initial values of the energy density and shear tensor at the initial time of

The Quark-Gluon-Plasma Liquid

, 2004
The quark-gluon plasma close to the critical temperature is a strongly interacting system. Using strongly coupled, classical, non-relativistic plasmas as an analogy, we argue that the quark-gluon plasma is in the liquid phase.

Dilepton Production from Rho-Mesons in a Quark-Gluon Plasma

, 1999
Assuming that rho-mesons exist in a quark-gluon plasma close to the QCD phase transition, we calculate the dilepton production rate from quark-antiquark annihilation via a rho-meson state using Vector Meson Dominance.
