Abstract
This Letter presents the first experimental observation of the attractive strong interaction between a proton and a multistrange baryon (hyperon) Ξ-. The result is extracted from two-particle correlations of combined p-Ξ- ⊕p-Ξ+ pairs measured in p-Pb collisions at √sNN=5.02 TeV at the LHC with ALICE. The measured correlation function is compared
