Transport Properties of the Quark-Gluon Plasma -- A Lattice QCD Perspective

Understand

Transport properties of a thermal medium determine how its conserved charge densities (for instance the electric charge, energy or momentum) evolve as a function of time and eventually relax back to their equilibrium values.

• Here the transport properties of the quark-gluon plasma are reviewed from a theoretical perspective.
• The latter play a key role in the description of heavy-ion collisions, and are an important ingredient in constraining particle production processes in the early universe.
• We place particular emphasis on lattice QCD calculations of conserved current correlators.
