英文摘要	The Multi-particle technique has been used to unravel the nature of the long-range collectivity in small collision systems. A large three-particle mixed-harmonic correlation (or event-plane correlation) signal was recently observed by the ATLAS Collaboration, but the role of non-flow correlations is not yet studied. We estimate the influence of non-flow correlations to the three-particle correlators in pp and p+Pb collisions using PYTHIA and HIDING models, and compare with the ATLAS results. The large non-flow effects from the jet and dijet production is found to be largely suppressed in p+Pb collisions using the subevent cumulant method by calculating the azimuthal correlation between two or more longitudinal pseudorapidity ranges. Depending on the experimental subevent method, however, the non-flow effects may still be significant in pp collisions. Future prospect to measure other multi-particle mixed-harmonic correlators in small systems are discussed. (C) 2019 The Authors. Published by Elsevier B.V.
