Proton-lead (pPb) collisions at a nucleon-nucleon center-of-mass energy sNN = 8.16 TeV and lead-lead (PbPb) collisions at sNN = 5.02 TeV collected by the CMS experiment at the LHC are investigated. Nonflow effects in the pPb collisions are studied by using a subevent cumulant analysis and by excluding events where a jet with transverse momentum greater than 20 GeV is present. The strange hadron v2 values extracted in pPb collisions via the four- and six-particle correlation method are found to be nearly identical, suggesting the collective behavior. Comparisons of the pPb and PbPb results for both strange hadrons and charged particles illustrate how event-by-event flow fluctuations depend on the system size. © The Author(s) 2023.Springer Science and Business Media Deutschland GmbH2023Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/12029https://doi.org/10.1007/jhep05(2023)0071029-8479enJournal of High Energy Physicsinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/12029
