摘要：

The data on e+e- annihilation are shown to be incompatible with an interpretation of the observed vector mesons as qqBAR excitations. It is necessary to consider mixing with some non-qqBAR system. Two specific models are considered: either four-quark states or hybrid states mixing with the conventional quark-antiquark excitations. Both models are compatible with the present e+e- annihilation data. It is possible to incorporate the 1.3 GeV J(PC) = 1-- state seen by LASS in the pipi channel in the four-quark model, but this is not possible with the hybrid model.
