Özet
Measurements of two-particle angular correlations between an identified strange hadron (K S 0 or Λ/Λ‾) 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 (s N N) of 5.02 TeV with the CMS detector at the LHC. The results are compared to semi-peripheral PbPb collision data at s N N= 2.76 TeV, covering similar charged-particle multiplicities in the events. The observed azimuthal correlations at large relative pseudorapidity are used to extract the second-order (v 2) and third-order (v 3) anisotropy harmonics of K S 0 and Λ/Λ‾ 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 …
