Two-particle femtoscopic correlation measurements of $\mathrm{K^{0}_{S}}$ and $\Lambda (\overline{\Lambda})$ particles in PbPb collisions at $\sqrt{s_{_{\mathrm{NN}}}}=5.02~\mathrm{TeV}$

Two-particle correlations as a function of relative momentum are presented for $\mathrm{K^{0}_{S}}$, $\Lambda$, and $\overline{\Lambda}$ strange hadrons produced in lead-lead collisions at $\sqrt{s_{_{\mathrm{NN}}}}=5.02~\mathrm{TeV}$. The data were obtained using the CMS detector at the LHC. Such correlations are sensitive to quantum statistics and to possible final-state interactions between the particles. Source radii extracted from $\mathrm{K^{0}_{S}K^{0}_{S}}$ correlations in different centrality regions are found to decrease in going from central to peripheral collisions. Strong-interaction scattering parameters (i.e., scattering length and effective range) are determined from $\Lambda\mathrm{K^{0}_{S}}\oplus\overline{\Lambda}\mathrm{K^{0}_{S}}$ and $\Lambda\Lambda\oplus\overline{\Lambda}\overline{\Lambda}$ correlations using the Lednicky-Lyuboshits model and compared to other experimental and theoretical results.
