Abstract (data abstract)

Two-particle correlations are presented for $\mathrm{K^{0}_{S}}$, $\Lambda$, and $\overline{\Lambda}$ strange hadrons as a function of relative momentum in lead-lead collisions at $\sqrt{s_{_{\mathrm{NN}}}} = 5.02$ TeV. The dataset corresponds to an integrated luminosity of 0.607 $\mathrm{nb}^{-1}$ and was collected using the CMS detector at the CERN LHC. Such correlations are sensitive to quantum statistics and to final-state interactions between the particles. The source size extracted from the $\mathrm{K^{0}_{S}K^{0}_{S}}$ correlations is found to decrease from 4 to 1 fm in going from central to peripheral collisions. Strong interaction scattering parameters (i.e., scattering length and effective range) are determined from the $\Lambda\mathrm{K^{0}_{S}}$ and $\Lambda\Lambda$ (including their charge conjugates) correlations using the Lednicky--Lyuboshits model and are compared to theoretical and other experimental results.
