The study of baryon-baryon interactions are of fundamental importance to understand existence of strangelets in heavy-ion collisions and various exotic hadrons, modeling of astronomical objects such as neutron stars. A detailed knowledge of nucleon-nucleon (NN) potentials exists in literature, however very little is known about interactions between anti-nucleons. Similarly lack of scattering data for hyperon-nucleon (YN) and multi-strange hyperon-hyperon (YY) systems makes it difficult to construct YN and YY potentials. In heavy-ion collisions, a large number of baryons are produced in each nucleus-nucleus collision, which allows us to study the NN, YN and YY interactions. Measurements of two-particle correlation function are used to study the space-time dynamics of the source created in heavy-ion collisions. At low relative momentum, the two-particle correlations are effected by the Final State Interactions (FSI), making it possible to measure FSI between NN, YN and YY. In this talk, a novel method to use measurement of the two-particle correlation function in heavy-ion collisions to understand these interactions and their implications on the existence of exotic dibaryons will be discussed.
