摘要：
The momentum correlation functions of baryon pairs, which reflects the baryon-baryon interaction at low energies, are investigated for multistrangeness 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.
