Description
Measurements of collective flow in intermediate-size collision systems such as OO and NeNe are crucial for understanding the origin of collectivity in small systems and its evolution with collision system size. Using data collected by the CMS experiment at the LHC, flow coefficients of charged particles ($n=2,3$) are measured in OO and NeNe collisions using two- and multi-particle correlation techniques as functions of centrality. In addition, collective flow measurements of strange hadrons are presented to investigate the particle-species dependence. The results are compared with pp, pPb, and PbPb collisions, as well as with theoretical calculations, providing new insights into the origin of collectivity in small systems and information on the nuclear structure of oxygen and neon nuclei.
