Multihadron decays of new mesons

We discuss the hadronic decays of the new I = 0 mesons seen in e+e-: J(psi) or psi' with G = - and P/sub c/ (chi) or X with G = +. We present some isospin inequalities for I = 0 pure pionic final states, and a discussion of K anti K and eta, eta' fractions. We also present a statistical-model analysis of pion final states, and conclude that a large fraction of hadronic J(psi) decays contain something besides pions and K anti K: probably eta and eta', possibly radiative modes
