Abstract: (Springer)
The groupSU4 is probably the most straightforward and economical generalization ofSU3 which allows for basic triplets of integral charges. In this paper we analyse in detail the predictions of a few models for strong interactions based ouSU4. In addition to the usual (nonpeculiar) eightfold-way particles new peculiar particles are predicted. However they can be allowed to be created and to decay semi-strongly by the mass-breaking interactions. Mass relations are obtained. It is pointed out that some difficulties concerning these mass formulae occur when one tries to attribute the ρ, K*, ω and ϕ vector mesons to the regular representation ofSU4.References(7)
