| Abstract: The collective behavior of $\mathrm{K^0_S}$ and $\Lambda/\bar{\Lambda}$ strange hadrons is studied using the scalar-product and multiparticle correlation methods. Proton-lead (pPb) collisions at 8.16 TeV and lead-lead collisions at 5.02 TeV are studied. The data samples were collected by the CMS experiment at the CERN LHC. Nonflow effects in the pPb collisions are investigated by a subevent cumulant analysis and by including a veto on events where a jet with $p_{\mathrm{T}} > $ 20 GeV is observed. For the first time, the collectivity of strange particles is observed in proton-lead collisions. A comparison of the proton-lead and lead-lead results for both strange particles and charged-hadrons is used to show how flow fluctuations are affected by system size. | ||
