DESCRIPTION:Speakers: Raghunath Pradhan (Indian Institute of Technology Ma
 dras (IN))\nThe two-particle correlations as a function of relative moment
 a of identified hadrons involving $\\mathrm{K^{0}_{S}}$ and $\\Lambda/\\ba
 r{\\Lambda}$ are measured in PbPb collision at $\\sqrt{s_{_{\\mathrm{NN}}}
 } =$ 5.02 TeV with the data samples collected by the CMS experiment at the
  LHC. Such correlations are sensitive to quantum statistics and possible f
 inal state interactions between the particles. The shape of the correlatio
 n function is observed to vary largely for different particle pairs\, reve
 aling the effect of the strong final state interaction in each case. The s
 ource radii are extracted from $\\mathrm{K^{0}_{S}K^{0}_{S}}$ correlations
  in different centrality regions and found to decrease from central to per
 ipheral collisions. The strong interaction scattering parameters are extra
 cted from $\\mathrm{K^{0}_{S}K^{0}_{S}}$\, $\\Lambda\\mathrm{K^{0}_{S}}\\o
 plus\\bar{\\Lambda}\\mathrm{K^{0}_{S}}$\, $\\Lambda\\Lambda\\oplus\\bar{\\
 Lambda}\\bar{\\Lambda}$ and $\\Lambda\\bar{\\Lambda}$ correlations using t
 he Lednicky-Lyuboshits model\, and compared with other experimental and th
 eoretical results. The scattering parameters indicate that the $\\Lambda\\
 Lambda\\oplus\\bar{\\Lambda}\\bar{\\Lambda}$ is attractive and that the $\
 \Lambda\\mathrm{K^{0}_{S}}\\oplus\\bar{\\Lambda}\\mathrm{K^{0}_{S}}$ inter
 action is repulsive.\n\nhttps://events.vecc.gov.in/event/18/contributions/
