We investigate and momentum correlations in high-energy collisions to elucidate the nature of and X(3872) exotic hadrons. Single range Gaussian potentials with the channel couplings to the isospin partners are constructed based on the empirical data within the pure hadronic-molecule picture. The momentum correlation functions of the , , , and pairs are computed with including the coupled-channel effects. We discuss how the nature of the exotic states are reflected in the behaviors of the correlation results.
