Exclusive hadron production in e+e- collisions up to the J/psi energy
N. N. Achasov, A. A. Kozhevnikov
Abstract
The predictions are presented for the diagonal and transition form factors of light hadrons in the time-like region up to the production threshold of an open charm quantum number. The comparison with existing data on the decays of J/psi and psi(2S) mesons into such hadrons shows that some new resonance structures may be present in the mass range between 2 GeV and the J/psi mass. Searching them may help in a better understanding of the mass spectrum in quark models, and in revealing the details of the three-gluon mechanism of the OZI rule breaking.
