Are the exotic mesons and baryons, recently observed, a signature of quark-hadron duality ?

Preserved Fulltext
Narrow l o w mass exotic hadronic structures were recently observed in mesons, baryons and dibaryons. Narrow mesons, in the mass range 300M 750 MeV, were observed using the pp ! ppX reaction. Narrow baryons in the mass range 1000M 1400 MeV were observed using the pp ! p + X and dp ! ppX reactions. The statistical signi cances of these structures vary up to 4.6 standard deviations S.D. for mesons and up to 16.9 S.D. for baryons. These exotic states are associated with precursor quark decon nement.
