Measurement of strange particle femtoscopic correlations at the CMS experiment

The two particle correlations as a function of relative momenta of identified hadrons involving K-S(0) and Lambda/(Lambda) over bar are measured in PbPb collisions at root s(NN) = 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 (KSKS0)-K-0 correlations in different centrality regions and found to decrease from central to peripheral collisions. The strong interaction scattering parameters are extracted from Lambda K-S(0) circle plus (Lambda) over barK(S)(0) and (Lambda Lambda) over bar correlations using the LednickyLyuboshits model, and compared with other experimental and theoretical results.
