Ab. Clegg et A. Donnachie, HIGHER VECTOR-MESON STATES PRODUCED IN ELECTRON-POSITRON ANNIHILATION, Zeitschrift fur Physik. C, Particles and fields, 62(3), 1994, pp. 455-469
A summary is presented of analyses of e+e- annihilation data, some of
which have been previously published and some of which are new. The ob
ject of these analyses is to establish the existence and decay modes o
f vector mesons which couple strongly to e+e-. The systematic informat
ion so obtained is used to check th obvious hypothesis that this set o
f vector mesons forms ideally mixed nonets of qqBAR states. This hypot
hesis does not appear to be tenable, and mixing with additional non-qq
BAR states appears to be required.
