Probing multistrange dibaryons with proton-omega correlations in high-energy heavy ion collisions

The two-particle momentum correlation between the proton (p ) and the omega baryon (Ω ) in high-energy heavy ion collisions is studied to unravel the possible spin-2 p Ω dibaryon recently suggested by lattice QCD simulations. The ratio of correlation functions between small and large collision systems, C_SL(Q ) , is proposed to be a new measure to extract the strong p Ω interaction without much contamination from the Coulomb attraction. Relevance of this quantity to the experimental observables in heavy ion collisions is also discussed.
