===== Description=====
EF07 studies the prospects for heavy-ion physics at future high energy heavy-ion colliders (such as RHIC, LHC, HL-LHC, and FCC) and the physics at future high energy electron-ion colliders (such as EIC, LHeC), with particular emphasis on the impact that those studies will have on the physics program of the Energy Frontier. 

===== Focus Questions ====
   * What can we learn from the jet and jet substructure measurements about the nature of the Quark-gluon plasma? How do we apply those techniques to the studies of jets and the  possible jet energy loss in EIC?
   * What is the best use of heavy-ion beams for the search of new physics?
   * What is the origin of the flow-like correlation from high multiplicity proton-proton and proton-ion collisions? Can we see it in ee and eA collisions?
   * What are the heavy flavor hadrons and quarkonia production mechanisms in ee, eA, pp, pA and AA collisions? What is the relevance of co-moving matter effects and recombination for the classical observables such as charm and beauty jet? 
   * What can we learn about the exotic hadron structure with pp, pA and AA collisions?
   * How do we use heavy-ion beam to improve the understanding of inclusive hadron and charm production? 
   * What is the connection to the new physics search at forward region and the studies of cosmic rays?
   * What is the emerging physics opportunity on proton tomography and gluon saturation with EIC? What are the relevant HEP applications?
