We study the momentum correlation functions of pΞ - and Λ Λ pairs produced in high-energy nuclear collisions by using the coupled-channel framework and the NΞ - Λ Λ coupled-channel baryon-baryon potentials recently obtained from lattice QCD calculations at almost physical quark masses. The calculated results are found to well describe the correlation function data from pp and pPb collisions. This agreement confirms the S= - 2 baryon-baryon potentials from lattice QCD and supports the existence of the H dibaryon as a virtual state around the NΞ threshold.
