Non-equilibrium phenomena and thermalisation in Quantum Chromodynamics

Aleksas Mazeliauskas

Heidelberg University
Morning

Microseconds after the Big Bang, no nucleons yet existed, and the Universe was filled with plasma made of quarks and gluons--the fundamental degrees of freedom of strong interactions. Astonishingly, the high-energy collisions of heavy nuclei recreate the same extreme conditions on Earth. The heavy-ion experiments at BNL’s Relativistic Heavy-Ion Collider (RHIC) and CERN’s Large Hadron Collider (LHC), therefore, provide us with a unique opportunity to study the non-equilibrium evolution of Quantum Chromodynamics (QCD)---the theory of strong force. In these lectures, I will review how different effective descriptions of QCD (classical-statistical field theory, QCD kinetic theory and viscous hydrodynamics) allow us to investigate the creation and thermalisation of QCD matter.
