  The momentum correlation functions of baryon pairs, which reflects the
baryon-baryon interaction at low energies, are investigated for
multi-strangeness pairs ($\Omega\Omega$ and $N\Omega$) produced in relativistic
heavy-ion collisions. We calculate the correlation functions based on an
expanding source model constrained by single-particle distributions. The
interaction potentials are taken from those obtained from recent lattice QCD
calculations at nearly physical quark masses. Experimental measurements of
these correlation functions for different system sizes will help to disentangle
the strong interaction between baryons and to unravel the possible existence of
strange dibaryons.
