Modified Quark Models

Conference paper
Part of the Acta Physica Austriaca book series (FEWBODY, volume 6/1969)

Abstract

We discuss the implications of the splitting of the A2 resonance. It leads us to theories where either a 1−+ or another 2 resonance are present. The 1−+ is included in the Gell-Mann-Zweig (4) scheme that we describe in some detail. An additional 2++ can be provided by many models, one of which — the giant quark model — is shortly discussed.
