Multihadron decays of new mesons

We discuss the hadronic decays of the new I=0 mesons seen in e+e-:J(ψ) or ψ′ with G=- and Pc (χ) or X with G=+. We present some isospin inequalities for I=0 pure pionic final states, and a discussion of KK̄ and η, η′ fractions. We also present a statistical-model analysis of pion final states, and conclude that a large fraction of hadronic J(ψ) decays contain something besides pions and KK̄- probably η and η′, possibly radiative modes.
