Role of Time‐Varying Magnetic Field on QGP Equation of State

Advances in High Energy Physics, Volume 2024, Issue 1, 2024.
The phase diagram of quantum chromodynamics (QCD) and its associated thermodynamic properties of quark‐gluon plasma (QGP) are studied in the presence of time‐dependent magnetic field. The study plays a pivotal role in the field of cosmology, astrophysics, and heavy‐ion collisions. In order to explore the structure of quark‐gluon plasma to deal with the

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 ...

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 ...

Relativistic hydrodynamic attractors with broken symmetries: non-conformal and non-homogeneous

Journal of High Energy Physics, 2017
Standard textbooks will state that hydrodynamics requires near-equilibrium to be applicable. Recently, however, out-of-equilibrium attractor solutions for hydrodynamics have been found in kinetic theory and holography in systems with a high degree of ...

Heavy quark energy loss in the quark-gluon plasma in the Moller theory

European Physical Journal C: Particles and Fields, 2020
We study the energy loss of a heavy quark propagating in the quark-gluon plasma (QGP) in the framework of the Moller theory, including possible large Coulomb logarithms as a perturbation to BDMPSZ bremsstrahlung, described in the harmonic oscillator (HO)

Multi-partonic medium induced cascades in expanding media

European Physical Journal C: Particles and Fields, 2022
Going beyond the simplified gluonic cascades, we introduce both gluon and quark degrees of freedom for partonic cascades inside the medium. We then solve the set of coupled evolution equations numerically with splitting kernels calculated for static ...

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.

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.

Fluid dynamics of charm quarks from heavy to light-ion collisions [PDF]

EPJ Web of Conferences
Heavy quarks are powerful tools to characterize the quark-gluon plasma (QGP) produced in relativistic nuclear collisions. By exploiting a mapping between transport theory and hydrodynamics, we developed a fluiddynamic description of heavy-quark diffusion

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.
