We present a systematic procedure for analyzing cumulants to arbitrary order in the context of heavy-ion collisions. It generalizes and improves existing procedures in many respects. In particular, particles which are correlated are allowed to belong to different phase-space windows, which may overlap. It also allows for the analysis of cumulants at any order, using a simple algorithm rather than complicated expressions to be derived and coded by hand. In the case of azimuthal correlations, it automatically corrects to leading order for detector non-uniformity, and it is useful for numerous other applications as well. We discuss several of these applications: anisotropic flow, event-plane correlations, symmetric cumulants, net baryon and net charge fluctuations.

  1. Evidence for similar collectivity of high transverse momentum particles in pPb and PbPb collisions

    nucl-ex 2025-02 accept novelty 7.0 of 10

    Four-particle correlations reveal similar high-pT elliptic flow in pPb and PbPb collisions, suggesting a common origin for high-pT collectivity.

  2. Correlation between particle spectra and elliptic flow

    nucl-th 2025-06 conditional novelty 6.0 of 10

    A new three-particle observable, v02(pT), correlates the hadron spectrum with elliptic flow and is predicted to show a mass-ordering inversion at low pT in Pb+Pb collisions.
