$ \mathrm{K^0_S} $ and $ \Lambda $ ($ \overline{\Lambda} $) two-particle femtoscopic correlations in PbPb collisions at $ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}} = $ 5.02 TeV

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 a nucleon-nucleon center-of-mass energy of 5.02 TeV. The dataset corresponds to an integrated luminosity of 0.607 nb$^{-1}$ and was collected using the CMS detector at the CERN LHC. These correlations are sensitive to quantum statistics and to final-state interactions between the particles. The source size extracted from the $ \mathrm{K^0_S}\mathrm{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-Lyuboshitz model and are compared to theoretical and other experimental results.
