Gluon Condensate and Non-Perturbative Quark-Photon Vertex [PDF]

open access: yes, 1999
We evaluate the quark-photon vertex non-perturbatively taking into account the gluon condensate at finite temperature. This vertex is related to the previously derived effective quark propagator by a QED like Ward-Takahashi identity.

Dissipative phenomena in quark-gluon plasmas [PDF]

open access: yesPhysical Review D, 1985
Transport coefficients of small-chemical-potential quark-gluon plasmas are estimated and dissipative corrections to the scaling hydrodynamic equations for ultrarelativistic nuclear collisions are studied. The absence of heat-conduction phenomena is clarified. Lower and upper bounds on the shear-viscosity coefficient are derived.

Clustering of Color Sources and the Equation of State of the QGP

open access: yesEPJ Web of Conferences, 2014
Possible phase transition of strongly interacting matter from hadron to a quark-gluon plasma state have in the past received considerable interest. It has been suggested that this problem might be treated by percolation theory.

Evolution of the mean jet shape and dijet asymmetry distribution of an ensemble of holographic jets in strongly coupled plasma

open access: yesJournal of High Energy Physics, 2018
Some of the most important experimentally accessible probes of the quark- gluon plasma (QGP) produced in heavy ion collisions come from the analysis of how the shape and energy of sprays of energetic particles produced within a cone with a specified ...

Early thermalization of quark-gluon matter by elastic 3-to-3 scattering

open access: yes, 2013
The early thermalization is crucial to the quark-gluon plasma as a perfect liquid and results from many-body scattering. We calculate squared amplitudes for elastic parton-parton-parton scattering in perturbative QCD. Transport equations with the squared

QUARK-GLUON PLASMA AND THERMALIZATION [PDF]

open access: yesInternational Journal of Modern Physics E, 2007
In these lectures, I will attempt a pedagogical and qualitative introduction to the theory of equilibrium and thermalization of quark-gluon plasmas. I assume only that the reader is familiar with quantum field theory at zero temperature and with QCD as the theory of the strong interactions.

Strongly Coupled Plasmas in High-Energy Physics

open access: yes, 2003
One of the main activities in high-energy and nuclear physics is the search for the so-called quark-gluon plasma, a new state of matter which should have existed a few microseconds after the Big Bang.

Equation of state of quark-gluon plasma using a simple phenomenological model

open access: yesEPJ Web of Conferences, 2018
The equation of state (EoS) of quark-gluon plasma (QGP) using a phenomenological model is studied in which finite value of quark mass is modified as effective mass.
