| Abstract | Quantum chromodynamics (QCD) on the lattice predicts that at high temperatures and energy densities, hadronic matter undergoes a phase transition and turns into a state of deconfined quarks and gluons known as quark-gluon plasma (QGP). This state of matter is typically thought to be created in the collisions of two heavy nuclei at ultrarelativistic energies, like the ones reached at the LHC. Despite the multiyear effort, much remains to be learned about parton densities in nuclei, the search for the possible onset of parton saturation, how the properties of QGP emerge at a microscopic level from the interactions among the individual partons and how subsequently vary across its phase diagram. The ATLAS and CMS Collaborations fully exploit the opportunities offered by high-density QCD studies with ion and proton beams that allow the study of cold nuclear matter effects, the onset of nuclear saturation, and long-range correlations. Additionally, experiments put emphasis on the examination of hadrons at high transverse momentum, fully reconstructed jets, heavy quarkonia, open heavy flavor particles, and jet quenching. Altogether, measurements at varying length scales provide quantitative information about the strongly coupled QGP, complementing the bulk and collective observables of the soft sector. |
