Description
We investigate the possibilities of identifying exotic hadrons in relativistic heavy ion collisions by studying the production yields of a selected set of exotic hadron candidates. We find that the yields of exotic hadrons are strongly dependent on their structures; we show that the hadron yield is typically an order of magnitude smaller compared to the statistical model prediction when it is a compact multi-quark state, and larger by a factor of two or more for a loosely bound hadronic molecule. We thereby suggest that studying the yields of exotic hadrons in relativistic heavy ion collision offers a promising solution to the problem of identifying hadronic molecular states and exotic hadrons with multiquark components [1, 2].
