We present the first measurement of the proton- correlation function in heavy-ion collisions for central (0-40%) and peripheral (40-80%) Au+Au collisions at $$\sqrt{s}$$$$_{NN}$$ =200 GeV by the STAR experiment at the Relativistic Heavy-Ion Collider (RHIC). Predictions for the ratio of peripheral collisions to central collisions for the proton-correlation function are sensitive to the presence of a nucleon-bound state. These predictions are based on the proton- interaction extracted from (2+1)-avor lattice QCD calculations at the physical point. The measured ratio of proton-correlation function from peripheral (small system) to central (large system) collisions is less than unity for relative momentum smaller than 40 MeV/c. Comparison of our measured correlation ratio with the theoretical calculation slightly favors a proton-Omega bound system with a binding energy of ~ 27 MeV.
