A fresh look at exotics

Simple quark model considerations suggest that the least massive oxotic mesons and baryons may occur close to the nucleon-antinucleon and nucleon-nucleon-antinucleon thresholds respectively. The fact that such channels are energetically open for the decay of these exotics means that both production and decay can proceed via allowed duality diagrams. We suggest three specific reactions which may permit their detection.
