Abstract

We discuss the exotic hadron structure and hadron-hadron interactions in view of heavy-ion collisions. First, we demonstrate that a hadronic molecule with a large spatial size would be produced more abundantly in the coalescence model compared with the statistical model result. Secondly, we constrain the ΛΛ interaction by using recently measured ΛΛ correlation data. We find that the RHIC-STAR data favor the ΛΛ scattering parameters in the range 1/a0 ≤ - 0.8 fm -1 and reff ≥ 3 fm.
