Abstract
The first experimental information on the strong interaction between Λ and Ξ− strange baryons is presented in this Letter. The correlation function of Λ–Ξ− and Λ‾–Ξ‾+ pairs produced in high-multiplicity proton–proton (pp) collisions at s=13 TeV at the LHC is measured as a function of the relative momentum of the
