N - Ω interaction from high-energy heavy ion collisions

We discuss possible observation of the N - Ω interaction from intensity correlation function in high energy heavy ion collisions. Recently a lattice QCD simulation by the HAL QCD collaboration predicts the existence of a N - Ω bound state in the ⁵S₂ channel. We adopt the N - Ω interaction potential obtained by the lattice simulation and use it to calculate the N - Ω correlation function. We also study the variation of the correlation function with respect to the change of the binding energy and scattering parameters. Our result indicates that heavy ion collisions at RHIC and LHC may provide information on the possible existence of the N - Ω dibaryon. (author)
