Mass and spin formula for quasi-stable high-mass mesons from dual resonance models. [Stability, Veneziaro model]
It is shown that the generalized Veneziano model predicts the existence of quasi-stable high mass mesons with definite masses and spins, which have their lowest-multiplicity decay-modes suppressed. Although the predicted degree of stability is less than experimentally required, proper introduction of internal quantum numbers into the model would likely enhance it. Besides psi (3.1) and psi' (3.7), relatively stable vector mesons of higher masses are expected, with the next one at a mass of approximately equal to 6 GeV.
