Dynamical violation of the Zweig rule and the energy dependence of pi /sup -/p to phi n

The large magnitude and rapid decrease with energy of sigma ( pi /sup -/p to phi n) in the momentum range <6 GeV/c indicate a dynamical breaking of the Zweig rule. An explicit box diagram amplitude is provided for this process. Zweig's rule is obeyed exactly at all vertices. The size and rap...

description The large magnitude and rapid decrease with energy of sigma ( pi /sup -/p to phi n) in the momentum range <6 GeV/c indicate a dynamical breaking of the Zweig rule. An explicit box diagram amplitude is provided for this process. Zweig's rule is obeyed exactly at all vertices. The size and rapid fall of the cross section are explained in terms of s-channel thresholds and duality cancellations in the intermediate states of the box. (8 refs).
