Experimental results from the LHC and RHIC colliders, together with novel theoretical tools developed in the last few years, are leading to an unprecedented knowledge of the collective dynamics at play in high-energy nuclear and hadronic collisions. Progress in our understanding of the initial-state of strongly interacting matter, from the saturated partonic structure of nuclei to its hydrodynamical evolution, is remarkable. The latest results from (p)dAu collisions at RHIC, pPb and high-multiplicity pp at the LHC carry hallmarks of collective behaviour akin to those observed in AA collisions and commonly attributed to the formation of QGP. A comprehensive understanding of the interplay of QGP collectivity with intrinsic initial state complexity remains elusive. The meeting will be focused on the discussion of the present experimental and theoretical knowledge of the partonic structure of protons and nuclei; the corresponding conditions at the initial stages of the collision, including the role and nature of fluctuations and correlations; the subsequent hydrodynamical evolution; the determination of viscosity or other medium properties; and the emergence of collective behaviour in small systems. Providing a framework for cross-talk among different subfields is one of the main goals of the conference.


  • Partonic structure of protons and nuclei.
  • The initial stages of heavy-ion collisions.
