abstract = {Recent measurements of the correlations between flow harmonics obtained using four-particle symmetric cumulants
and three-particle asymmetric cumulants with the ATLAS detector at the LHC are described. The data sets of pp, p+Pb
and peripheral Pb+Pb collisions at various energies are analyzed, aiming to probe the long-range collective nature of
multi-particle production in small systems. The sensitivity of the standard cumulant method to non-flow correlations is
investigated by introducing the subevents method. A systematic reduction of non-flow effects is observed when using the
two-subevent method. Further reduction is observed with the three-subevent method that is consistent with the results
obtained with the four-subevent one. A negative correlation between v2 and v3 and a positive correlation between v2
and v4, for all studied collision systems and over full multiplicity range, is observed. The correlation strength computed
as symmetric cumulants normalized by the (v2n) is similar for all collision systems and weakly depends on multiplicity.
These measurements provide new evidence for long-range multi-particle collectivity in small collision systems and
quantify the nature of its event-by-event fluctuations.},
