Description
Observation of a long-range, near-side, two-particle correlation (known as the “Ridge”) in high-multiplicity pp and pPb collisions opened up new opportunities of exploring novel QCD dynamics in small collision systems. CMS has excellent capabilities of reconstructing weakly decay strange hadrons such as $K^0_s$, $\Lambda$ and $\Xi^-$. Studies of strange hadron production and correlations in small colliding systems provide crucial insights to the physical origin of novel collective phenomena. New results of pT spectra and long-range two-particle correlations for charged particles and identified strange hadrons in high-multiplicity pp and pPb collisions are presented. The data at various collision energies for pp and pPb collisions are compared to those obtained in large PbPb colliding systems. A measurement of multi-paricle cumulant in pp and pPb is also presented to explore the collective nature of the long-range correlations.
