Collective dynamics in relativistic nuclear collisions studied with ALICE at the LHC

ALICE is a detector designed to study strongly interacting matter at extreme temperatures and energy densities, where the quark-gluon plasma (QGP) is formed, but it also allows one to perform unique measurements in proton– proton and proton–lead collisions. In these proceedings, we present a selected set of correlation measurements done by ALICE, in both heavy-ion collisions and in small collision systems. The results indicate that long-range correlations are present in pp and p–Pb collisions.The analysis of the collective behaviour in small and large collision systems could shed some light on the formation and evolution of the QGP.
