| Summary: | The two particle correlations as a function of relative momenta of identified hadrons involving Ks0KS0 and Λ/Λ¯Λ/Λ¯ are measured in PbPb collisions at √SNN = 5.02 TeVsNN=5.02 TeV with the data samples collected by the CMS experiment at the LHC. Such correlations are sensitive to the quantum statistics and possible final state interactions between the particles. The source radii are extracted from KS0KS0KS0KS0 correlations in different centrality regions and found to decrease from central to peripheral collisions. The strong interaction scattering parameters are extracted from ΛKS0KS0⊕Λ¯KS0ΛKS0⊕Λ¯KS0 and ΛΛ⊕ΛΛ¯ΛΛ⊕ΛΛ¯ correlations using the Lednicky-Lyuboshits model, and compared with other experimental and theoretical results. In addition, we present results for the source radii of charged hadrons considering the Levy type source distributions in PbPb collisions at √SNN = 5.02 TeVsNN=5.02 TeV. |
