Description
Measurements of low-pT (< 5 GeV) particle production have provided
valuable insight on the production and evolution of the quark-gluon
plasma in Pb+Pb collisions at the LHC. In particular, measurements of
elliptic and higher order collective flow imprinted on the azimuthal angle
distributions of low-pT particles directly probe the strongly-coupled
dynamics of the quark gluon plasma and test hydrodynamic model
descriptions of its evolution. The large acceptance of
detectors like ATLAS have made it possible to measure flow
event-by-event and to determine the correlations between different
harmonics. Recent measurements of low-pT particle production and
multi-particle correlations in proton-lead collisions have shown
features similar to the collective flow observed in Pb+Pb collisions.
Results will be presented from a variety of single and multi-particle
measurements in Pb+Pb and proton-Pb collisions that probe the
collective dynamics of the quark gluon plasma and possibly provide
evidence for collectivity in even small systems.
