Book excerpt: The measurements of two-particle angular correlations between an identified strange hadron ( K0s or [Lambda]/[Lambda]- ) and a charged particle, emitted in pPb collisions, are presented over a wide range in pseudorapidity and full azimuth. The data, corresponding to an integrated luminosity of approximately 35 nb-1, were collected at a nucleon-nucleon center-of-mass energy (√sNN ) of 5.02 TeV with the CMS detector at the LHC. Our results are compared to semi-peripheral PbPb collision data at √sNN , covering similar charged-particle multiplicities in the events. The observed azimuthal correlations at large relative pseudorapidity are used to extract the second-order (v2) and third-order (v3) anisotropy harmonics of K0s and [Lambda]/[Lambda]- particles. These quantities are studied as a function of the charged-particle multiplicity in the event and the transverse momentum of the particles. For high-multiplicity pPb events, a clear particle species dependence of v2 and v3 is observed. For pT
