Exotic hadrons and hadron-hadron interactions in heavy-ion collisions
Additional Document Info
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 interaction by using recently measured correlation data. We find that the RHIC-STAR data favor the scattering parameters in the range 1/a0 - 0.8 fm -1 and reff 3 fm. 2013 Elsevier B.V.
