Transport coefficients in quantum chromodynamics
Relativistic kinetic theory provides a transport equation for classical, spinless, colored particles in a non-Abelian external field. We review the methods of solution used in the literature to find the transport coefficients for quark and gluon systems. Most authors use the relaxation time …

A Detailed Treatment of the Measurement of Transport Coefficients in Transient Grating Experiments
This thesis treats the measurement of transport coefficients in transient grating experiments and is organized into 3 parts. Part 1 provides a brief review of the thermodynamic-phenomenological theory relevant for a correct description of the Soret effect. It comprises the formulation of the first …

Probing the Quark-Gluon Plasma properties through Heavy Quarks' dynamics: transport coefficients and elliptic flow
La Cromodinamica Quantistica (QCD) è la teoria di gauge non-abeliana che nell'ambito del Modello Standard descrive l'interazione forte fra quark e gluoni. La QCD possiede due proprietà principali: il confinamento e la libertà asintotica. A causa del confinamento quark e gluoni nella materia …
