Quark Gluon Plasma Diagnostics in a Successive Equilibrium Scenario [PDF]

, 1997
The relativistic Fokker Planck equation has been used to study the evolution of the quark distribution in the quark gluon phase expected to be formed in ultra-relativistic heavy ion collisions.

Conductivities of magnetic quark-gluon plasma at strong coupling [PDF]

Physical Review D, 2018
In the presence of a strong magnetic field, the quark gluon plasma is magnetized, leading to anisotropic transport coefficients. In this work, we focus on the effect of magnetization on electric conductivity, ignoring the possible contribution from the ...

Origin of Temperature of Quark-Gluon Plasma in Heavy Ion Collisions

, 2015
Initially produced quark-gluon matter at RHIC and LHC does not have a temperature. A quark-gluon plasma has a high temperature. From this quark-gluon matter to the quark-gluon plasma is the early thermalization or the rapid creation of temperature ...

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.

The effect of weak magnetic photon emission from quark-gluon plasma

Physics Letters B
We propose a novel effect that accounts for the photon emission from a quark-gluon plasma in the presence of a weak external magnetic field. Although the weak magnetic photon emission from quark-gluon plasma only leads to a small correction to the photon

Quark-Gluon Plasma Fireball

, 2000
Lattice-QCD results provide an opportunity to model, and extrapolate to finite baryon density, the properties of the quark-gluon plasma (QGP). Upon fixing the scale of the thermal coupling constant and vacuum energy to the lattice data, the properties of

Far-off-equilibrium early-stage dynamics in high-energy nuclear collisions [PDF]

EPJ Web of Conferences
We explore the far-off-equilibrium aspects of the (1+1)-dimensional early-stage evolution of a weakly-coupled quark-gluon plasma using kinetic theory and hydrodynamics.

Phenomenological Review on Quark–Gluon Plasma: Concepts vs. Observations [PDF]

, 2016
In this review, we present an up-to-date phenomenological summary of research developments in the physics of the Quark–Gluon Plasma (QGP). A short historical perspective and theoretical motivation for this rapidly developing field of contemporary ...
