A candidate for a four-quark vector-meson?

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

Previous claims for the existence of vector mesons with masses in the vicinity of 1100 MeV and 1300 MeV are reconsidered in the light of recent developments in the analysis and interpretation ofe + e − annihilation and diffractive photoproduction data. It is shown that these states are compatible with present evidence and can be incorporated in an extended mixing scheme of conventional\(q\bar q\) with unconventional\(qq\bar q \bar q\) states.
