Description

Decays of phi, f', psi and psi' which violate Zweig rule are discussed in the dual unitarisation scheme. One obtains the correct hierarchy of suppression associated with different topologies of the quark graphs and the observed pattern of SU(3) breaking. A simplified calculation already yields decay widths in semi-quantitative agreement with experiment. (Auth.)
