27 27 2.Production rates from Heavy Ion collisions can be used to distinguish mulitquark from usual and molecular configuration:  f0 can not be a pure multiquark configuration 3. Heavy multiquark states + Exotics can be observed at LHC Summary 4. May be high multiplicity p-A reaction can be useful to reduce background 1. Yields of light nuclei can be understood from conservation of S/N
