The inclusion of these inelastic channels provides good agreement with the data, showing a significant presence of the annihilation term down to zero momentum.\nPredictions obtained using the Lednick$\\'y$--Lyuboshits formula and scattering parameters obtained from\nheavy-ion collisions, hence mainly sensitive to elastic processes, are compared with the experimental $p-\\overline{\\Lambda}\\oplus \\Lambda-\\overline{p}$ and $\\Lambda-\\overline{\\Lambda}$ correlations. The model describes the $\\Lambda-\\overline{\\Lambda}$ data and underestimates the $p-\\overline{\\Lambda}\\oplus \\Lambda-\\overline{p}$ data in the region of momenta below 200 MeV/$c$.\nThe observed deviation indicates a different contribution of annihilation channels to the two systems containing strange hadrons.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.128683.v1/t1","@type":"Dataset","description":"$p-\\overline{p}$ correlation function in high-multiplicity pp collisions at $\\sqrt{s}=13$
