With the advent of the RHIC II and LHC programs, our field is entering a new discovery phase – it is therefore timely to take note of where we are with respect to our current state of knowledge of QCD matter and what the greatest theoretical challenges will be for the next few years.
This is the 2nd post in our series in which we have asked a number of leading scientists in our field to identify the 3-5 most important challenges which the field of hot and dense QCD matter theory has to address (click here for the previous post by Larry McLerran)
- Development of a transport code for the deconfined phase of relativistic heavy-ion collisions which including mean fields, i.e. a code which treats soft and hard QCD phenomena consistently.
- Development of a full microscopic theory of hadronization across all energy/momentum scales (i.e. including formation of bulk matter, parton recombination, fragmentation and heavy flavor hadrons).
- Develop a fundamental understanding of the theory of dissipative relativistic hydrodynamics.
- Develop a transport formulation for the Glasma (i.e. how to describe the dynamics of a CGC-like initial state).
- If we consider AdS/CFT to be the right tool to derive non-perturbative QCD quantities – can this approach be extended to a true non-equilibrium setup beyond the extraction of transport coefficients for hydro?
