Light Vector Meson Spectroscopy

Abstract

The current situation for vector meson spectroscopy is outlined, and it is shown that the data are inconsistent with the generally-accepted model for meson decay. A possible resolution in terms of exotic (hybrid) mesons is given. Although this hypothesis resolves some of the issues, fresh theoretical questions are raised. It is argued that high-precision $e^{+}{e}^{-}$ annihilation data provide an excellent laboratory for studying many aspects of nonperturbative QCD.
